You realize that order is a keyword, right?

Assuming you change order to something else, the insert returns the OID
of the record just added. In psql this appears as something like this.
INSERT 36448 1
So, just read back the record.
SELECT pid FROM table WHERE OID = 36448;
The various interfaces give you methods to get this value back. Read the
docs for whichever interface you are using.
