Is there a way to return the oid of the last insert command?

Thanks,
Matt

The protocol does return the oid, as a string. You can see this when using
psql. I'm not sure what libpq function returns this value though.

In JDBC, there isn't an official way, but the 6.4 driver does have a
method to retrieve the oid (It's used internally with the new object
serialization code). Earler versions store the string, but don't use it,
and have no method to retrieve it.

Thanks for the help. I checked libpq, and just to follow up, it is quite
easy to get the oid of the last insert using the routine oidStatus.

I have added this to the TODO list:

* add a function to return the last inserted oid, for use in psql scripts

We need it for psql scripts. Things using libpq directly already have
access to this information.
