Last Id?

Hello all,

   I know how do do this in IBM DB2 and MySQL, but now my interrest has
shifted towards postgresql; I need to be able to insert a row, and find
out which id it was assigned. (I'm talking about using sequences here).

   I have seen a few "currval", "last_value", tricks and such, but they
aren't good enough, AFAICT, since they only work when I can guarantee
that no one else will insert a new record between the time that I insert
one, and query for the last_value.

   In IBM DB2 and MySQL there's a connection specific "last id" value
which can be queried. I assume there's something similar in postgresql
-- but what is it?
