Re: [HACKERS] How to get OID from INSERT in PL/PGSQL?

For what it's worth, psql will be able to do this in the next release. It
will look like this:

=> insert into foo values (...);
=> insert into bar values (:LastOid, ...);

which is even marginally SQL compliant as I understand. If you are daring
you can get the current snapshot and try it, but I wouldn't sign my life
away on it quite yet.

Everything(?) uses libpq more or less directly. It's just a matter of
interfacing your applicaton to the OidStatus function. The above psql does
just that.
