Re: Session Identifiers

Can be totally different if you use some connection pooler like pgpool or pgbouncer - these applications can reuse Postgres server sessions for more user sessions.

BTW, AFAIK, it's not possible to change the session authentication information by

using SET SESSION AUTHORIZATION [1] if the current user is not a superuser.

But it would be very nice to have a feature to change the session authorization

of current user even without superuser's privilege by supplying a password of

the user specified in SET SESSION AUTHORIZATION. This feature allows

to use PostgreSQL's native privileges via connection pools -- i.e. without

needs to open a dedicated connection for authenticated user. Is it possible

to implement it?
