Postgres process listing

If you’re used to SHOW PROCESSLIST; or mysqladmin processlist in MySQL, you might be searching for this same functionality in postgresql. Here’s the quick way to get a process list in postgresql:

Switch to the postgres user:

# su - postgres

Get into the postgres shell:

# psql

Then run a quick query:

select * from pg_stat_activity;

NOTE: To actually see the queries being run, you will need logging enabled (it’s disabled by default). I don’t know how to turn it on yet, so this post will be left open until I find out!
