Actually, it's tablename_columname_seq , unless that exceeds namedatalen. It
shouldn't. Mine never do... But if it does, there is an algorithm for truncating the
table and/or field name to fit.

You can call currval on the sequence that provided the value for the
primary key. It's guaranteed to be the last value retrieved from that
sequence *for your session*.
insert into table1 (f1, f2) values ('a', 'b');
select currval('table1_seq');
Use the name of your sequence. If the primary key is a SERIAL type,
then there will be a sequence in the background. I believe it's
tablename_seq or something like that.
