It took the OP to mean last insert as in randomly in the past, not as
part of current transaction. My fear is OP's schema has no way of
identifying time-of-insert, nor a monotonically increasing record id and
is hoping postgres has a some internal value that will return the most
recently inserted record. Without a table definition it's hard to say.
