Quick verdict
Use pgAdmin's dashboard when you need to see live activity and act on it, for example find a blocking session and cancel or terminate it. Use pgBadger when you need a report of what happened over hours or days, built from the server log, such as the slowest normalised queries, lock waits and temporary files. They are not substitutes: most PostgreSQL teams who use one would benefit from the other, and from pg_stat_statements for cumulative per-query statistics. Both are free under the PostgreSQL Licence.
pgAdmin 4 is the PostgreSQL project's administration and development tool, under the PostgreSQL Licence; the current release is 9.18. Alongside object management, the Query Tool and backup dialogs, its Dashboard tab gives, in the documentation's words, an active analysis of system statistics and usage statistics for the selected server or database: graphs of sessions, transactions per second, tuples in and out and block I/O, a panel of sessions, locks and prepared transactions, and the server configuration. Since version 7.8 a System Statistics tab shows CPU, memory and storage through the system_stats extension. See our pgAdmin review.
pgBadger describes itself as a PostgreSQL log analyser built for speed that produces detailed reports from PostgreSQL log files. It is a single Perl script, maintained by Gilles Darold under the PostgreSQL Licence; the latest release on GitHub is 13.2 (December 2025). It never connects to the database: it reads stderr, syslog, csvlog or jsonlog files (and formats such as pgBouncer, Amazon RDS and Google Cloud SQL logs), locally or over SSH, and writes interactive HTML reports or JSON.
Side by side
| Aspect | pgAdmin | pgBadger |
|---|---|---|
| Kind of tool | Desktop or web GUI for administration, with a live dashboard | Command-line log analyser that writes reports |
| Data source | Live connection to the server and its statistics | PostgreSQL log files only; no database connection |
| Time frame | Now: what is running and waiting while the dashboard is open | The past: whatever period the logs cover, with incremental daily and weekly reports |
| Query analysis | Current query per session; Query Tool with graphical EXPLAIN | Slowest, most frequent and most time-consuming normalised queries, with examples; auto_explain plans if logged |
| Locks and waits | Current locks and blocked sessions; cancel or terminate sessions | Lock waits logged over time (needs log_lock_waits) |
| Other reports | Configuration view; System Statistics via system_stats; optional AI Reports |
Connections, sessions, checkpoints, temporary files, autovacuum, errors |
| Setup on the server | A login with suitable privileges | Logging settings in postgresql.conf, which increase log volume |
| Licence and cost | Free, PostgreSQL Licence | Free, PostgreSQL Licence |
| Main trade-off | Immediate and interactive, but no history once you look away | Detailed history, but only as good as the logging you enabled, and never live |
Key differences
Different questions: "what is happening" versus "what happened"
pgAdmin's dashboard is a live view. It is the right place to answer "why is the application stuck right now": look at the session list, see which sessions are active or idle in transaction, check the locks panel, and cancel the query or terminate the session from the same screen. The documentation describes this as active analysis; it is not a store of history, so a spike that happened at 3 a.m. is gone by morning.
pgBadger answers the opposite question. Because it reads the log, it can tell you which normalised queries took the most total time yesterday, how many temporary files were written, when checkpoints ran, how many connections arrived per hour, and which errors occurred. Its incremental mode (-I) builds daily reports and cumulative weekly summaries, and -j parses in parallel. What it cannot do is show anything that was not logged.
The logging pgBadger needs
pgBadger depends on PostgreSQL logging that is mostly off by default. Its documentation asks for log_min_duration_statement (0 logs every statement; a higher threshold on busy servers), a log_line_prefix that includes a time escape (%t, %m or %n) and a process escape (%p or %c), and several event settings. The settings pgBadger documents, for stderr logging:
# postgresql.conf (PostgreSQL), settings documented by pgBadger
log_min_duration_statement = 0 # or e.g. 250ms on a busy server
log_line_prefix = '%t [%p]: user=%u,db=%d,app=%a,client=%h '
log_checkpoints = on
log_connections = on
log_disconnections = on
log_lock_waits = on
log_temp_files = 0
log_autovacuum_min_duration = 0
log_error_verbosity = default
lc_messages = 'C' # or 'en_US.UTF-8'pgBadger warns not to enable log_min_duration_statement, log_duration and log_statement together, because that produces wrong counter values and much larger logs, and notes that with log_statement = 'all' nothing is logged through log_min_duration_statement. Two PostgreSQL 18 details are worth knowing: log_checkpoints is already on by default, and log_connections is now a list of aspects (receipt, authentication, authorization, setup_durations, all), with on still accepted for backwards compatibility as the first three. Logging every statement costs disk space and I/O, so many teams start with a threshold such as 250 ms and lower it during an investigation.
Where pg_stat_statements fits
pg_stat_statements is the third piece. It is a PostgreSQL module that keeps cumulative planning and execution statistics per normalised statement in shared memory, so it covers every query without logging each one. It must be added to shared_preload_libraries (with compute_query_id on), which needs a restart, and then enabled with CREATE EXTENSION. The PostgreSQL documentation's own example finds the statements with the highest total time:
-- PostgreSQL: top statements by total execution time
SELECT query, calls, total_exec_time, rows,
100.0 * shared_blks_hit /
nullif(shared_blks_hit + shared_blks_read, 0) AS hit_percent
FROM pg_stat_statements
ORDER BY total_exec_time DESC
LIMIT 5;In practice the three complement each other: pg_stat_statements tells you which statements cost the most in total since the last reset, pgBadger shows when they ran, with example parameter values and the surrounding lock waits, temporary files and errors, and pgAdmin lets you see and stop what is running now and run EXPLAIN on a suspect query in the Query Tool. pgBadger does not read pg_stat_statements, and the pgAdmin dashboard does not chart it; you query it yourself or use a monitoring product that does. For more on reading plans, see performance tuning and SQL indexes.
Running them
pgAdmin runs as a desktop application or as a web server shared by a team, and needs a login on each PostgreSQL server; PostgreSQL shows other users' query text only to superusers and roles with sufficient privileges, such as members of pg_read_all_stats. From version 9.13, pgAdmin also offers optional AI Reports (security, performance and design) using a configured LLM provider (Anthropic, OpenAI, Ollama or Docker Model Runner); administrators can disable them. These are generated suggestions, not monitoring history.
pgBadger needs only Perl and access to the log files. It is typically run on a schedule (for example from cron) against the log directory or a remote host over SSH, and its HTML output is published somewhere the team can read. On managed services you first need to download or stream the logs; pgBadger documents formats for Amazon RDS and Google Cloud SQL logs.
Pricing and licensing
Both are free open source software under the PostgreSQL Licence, with no paid edition. pgAdmin is free in desktop and server mode. pgBadger is free; its cost is the extra log volume and storage from the logging settings it needs, and somewhere to run the script and host the reports.
Pricing checked on the vendors' official pages on 7 October 2026. Prices change; confirm before buying.
Where each one leads
pgAdmin strengths
- Live view of sessions, locks and transactions, with cancel and terminate actions
- Part of a full PostgreSQL administration tool: Query Tool, graphical EXPLAIN, backups, maintenance
- Needs no server configuration beyond a suitable login
- Desktop or shared web deployment
- System Statistics for CPU, memory and storage with the system_stats extension
pgBadger strengths
- Reports on any past period the logs cover, including incremental daily and weekly reports
- Normalised slowest, most frequent and most time-consuming queries with examples
- Covers locks, temporary files, checkpoints, autovacuum, connections and errors in one report
- No database connection or agent; reads local, remote or managed-service log files
- Single Perl script, parallel parsing and JSON output for other tools
Limitations
pgAdmin limitations
- No history: the dashboard shows only what is happening while you watch
- No ranking of queries over time; pg_stat_statements must be queried separately
- One server or database at a time, not an estate-wide monitor
- No alerting
pgBadger limitations
- Only sees what was logged; most required settings are off by default
- Logging all statements increases log size and I/O on busy servers
- Not live: reports are produced after the fact
- No alerting, and you host and schedule it yourself
When to choose each
Choose pgAdmin if
- You need to find and stop a blocking or runaway session now
- You want to check current load, connections and locks during an incident
- You also administer the server: objects, roles, backups and maintenance
- You cannot change logging settings on the server
Choose pgBadger if
- You need to know which queries were slowest or most expensive over a day or week
- You are investigating a past incident and have the logs
- You want regular reports on locks, temporary files, checkpoints and errors
- You want analysis without giving a tool a database login
When neither is right
- You need continuous monitoring with history, dashboards and alerts across many servers: see Prometheus vs Datadog and PostgreSQL monitoring tools.
- You want query-level monitoring linked to application traces: see Datadog vs New Relic and Database Monitoring vs APM.
- You want a free PostgreSQL GUI but not pgAdmin: see pgAdmin alternatives and DBeaver vs pgAdmin.
Final recommendation
pgAdmin and pgBadger are complements, not rivals. Keep pgAdmin (or another client) for live triage and administration, enable pg_stat_statements for cumulative per-query statistics, and configure logging so that pgBadger can report on what happened over time. If you need dashboards with history and alerting across servers, add a monitoring system on top; neither tool is one.
Frequently asked questions
Is pgBadger a replacement for pgAdmin?
No. pgBadger only analyses log files and writes reports; it cannot connect to a database, run queries or manage objects. pgAdmin is an administration GUI with a live dashboard. They are commonly used together.
What log_line_prefix does pgBadger need?
For stderr logs, at least a time escape and a process escape, for example log_line_prefix = '%t [%p]: '. pgBadger recommends adding user, database, application and client, for example '%t [%p]: user=%u,db=%d,app=%a,client=%h ', so reports can be broken down by them.
Does pgBadger use pg_stat_statements?
No. pgBadger reads only PostgreSQL log files. pg_stat_statements is a separate PostgreSQL module that keeps cumulative statistics per normalised statement in shared memory; you query it with SQL or through a monitoring tool.
Does pgAdmin keep monitoring history?
Its dashboard is documented as an active, live analysis of server and database statistics. It is not designed to keep history or send alerts; use a monitoring system for that.
Will logging every statement slow PostgreSQL down?
It adds log writing and disk use, which matters on busy servers; pgBadger's documentation suggests raising log_min_duration_statement above 0 in that case. We have not measured the overhead, which depends on workload and storage.
