Обсуждение: monitoring running queries?
Is there any way (besides ps) to view queries that are running on the PostgreSQL server? Something that actually output the query being run would be great. -- Brice Ruth WebProjkt, Inc. VP, Director of Internet Technology http://www.webprojkt.com/

You can set the logging option for query to 4, I believe, and it will log
the full query by whatever logging facility you are using (syslog,
redirected stdout or whatever). Take a look in the admin docs for
whatever version you are using. There's a lot fo stuff you can log.
If you are logging queries, you can open up the log file with tail -f and
monitor the log as queries are being made.

Its not working ... I looked at the admin docs and edited the pg_options file appropriately ... the following is what appears in /var/log/messages: postgres[23686]: read_pg_options: verbose=2,query=4,syslog=2 But no queries ... I sent SIG_HUP to postmaster, even restarted postmaster. The file /var/log/postgresql appears to be empty as well. -Brice "Brett W.

I don't know how you are starting postgreSQL, but I just have it redirect
everything to a log file under the postgres super user's directory:
nohup postmaster [options] >>server.log 2>&1 &
Make sure you don't use the -S option -- it detaches from the tty and you
will get no output!
