Technically yes. Practically - no.

You could redirect logs to syslog, and make syslog filter messages based
on user, but it's unlikely to work well.

Hi,

 

If you mean the “standard” logging system for PostgreSQL the reply is No. Parameter “log_filename” is of context “sighup” and can’t be modified by session…

Here are a couple of ideas that are outside of the direct question.

I believe you can target one or more users with the pgaudit extension.  Look for Session Audit Logging. 
Example "ALTER ROLE role_name SET pgaudit.log = 'all, -misc';". https://github.com/pgaudit/pgaudit#session-audit-logging 

Some clients such as psql will also allow you to write history per host / user.  ~/.psqlrc file add "\set HISTFILE ~/.psql_history_ :HOST _ :USER _ :DBNAME" for example.

Both of these should be well documented and relatively easy to test to see if they might be of some assistance for you.

Hope this helps.


Best regards,

Dan Smith

Thanks Dan Smith,
Will it log queries executed from PGADMIN? I think no.
