currval
Return the value most recently obtained by nextval for this sequence
in the current session. (An error is reported if nextval has never
been called for this sequence in this session.) Notice that because
this is returning a session-local value, it gives a predictable
answer whether or not other sessions have executed nextval since the
current session did.
