Обсуждение: Identify Login User & Permissions
I can't find in the docs or using Google how one can identify which user is currently logged in to psql. I search for the command that if for some reason I forget which user I am logged in as, rather than logging out of PostgreSQL, there has to be a command that shows me who I am and also what kind of special permissions my current user has. Can anyone please assist me or point me in the right direction?

That worked well: postgres=# SELECT current_user; current_user -------------- carlos (1 row) Do you know how I can verify what privileges or permissions 'carlos' has granted to him in PostgreSQL?

I don't have the entire answer. But here is a place to start: http://www.postgresql.org/docs/9.0/static/functions-info.html Note that there is a slight distinction between current_user and session_user. postgres=> select user, current_user, session_user; current_user | current_user | session_user --------------+--------------+-------------- broersr | broersr | broersr (1 row) -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug

You won't find a single command to do that. -- Guillaume http://www.postgresql.fr http://dalibo.com
