However, I agree that one of the drawbacks of this scheme would be
breaking the OID in the status string returned by INSERT and similar
commands. Not too big a deal, IMHO (users can still get the same effect
by specifying WITH OIDS, or toggling the GUC var)... </pre></blockquote> The users who don't know any better and expect
thatpg_getlastoid should return the last oid will have trouble.  There really should be alternative first, like binding
variablesand RETURNING INTO.  Is it on the TODO list by any chance?  <br /><blockquote
