Hi! Is there any function in PGSQL that returns an unique Session identifier of the actual session? For example a Bigint, or GUID, or etc? Can I get the living Session identifiers from PG? We have a little application that uses these infos which are basically came from another database system, and I will port this, but I don't know, how to do in PGSQL... In this app. we associated (stored) the session id to a special field in some tables. We can retreive the living session ids with a system functions. If a session died, these records have become irrelevant - we can delete them. If the session still alive, we don't touch them, only can read the content... I see adv_locks in pg, but because the quantity of locks are pre-determined by the server, I don't choose them. I better like a technic that cannot exhaust the number of persistent elements.
