If OIDs are dropped a mechanism for retrieving the primary key of the
last insert would be greatly appreciated. Heck, it would be useful
now (rather than returning OID).
I much prefer retrieving the sequence number after the insert than
before insert where the insert uses it. Especially when trigger
muckary is involved.

how restful it is to watch the cursor blink. Close your eyes. The
opinions stated above are yours. You cannot imagine why you ever felt
otherwise.
