Include All Queries In The Log File

The default log-level (log_statement setting) for a PostgreSQL server is none. Other valid log-levels for that setting are ddl, mod, and all.

If you want to see all the queries hitting a database, you'll want to set it to all. This can be set as a server-wide setting or it can be set on a per-session basis.

Because all is so noisy, I like to use it on a per-session basis when I'm in a situation where I know I'd like to see all queries.

> set log_statement = 'all';

After running that statement in my psql session, I can tail the log file to keep an eye on queries hitting the database.

Be sure that logging is enabled via the logging_collector as well.
