New feature proposal (trigger)

Dear PgSQL-Hackers,

I would like to propose a new feature which is missing in PgSQL but quite useful and nice to have (and exists in Oracle and probably in some other RDBMS), I speak about "Database Level" triggers: BeforePgStart, AfterPgStarted, OnLogin, OnSuccessfulLogin, BeforePGshutdown, OnLogOut - I just mentioned some of it but the final events could be different.

These DB Level triggers are quite useful for example if somebogy want to set some PG env. variables depends on user belonging to one or another role or want to track who/wen logged in/out, start a stored procedure AfterPgStarted and so on.

Thanks!
