/home/sas/src/php4/ext/pgsql/pgsql.c: In function `php_if_pg_getlastoid':
/home/sas/src/php4/ext/pgsql/pgsql.c:1260: `InvalidOid' undeclared (first use in this function)
/home/sas/src/php4/ext/pgsql/pgsql.c:1260: (Each undeclared identifier is reported only once
/home/sas/src/php4/ext/pgsql/pgsql.c:1260: for each function it appears in.)
InvalidOid is used to check the return value of PQoidValue().
src/interfaces/libpq/fe-exec.c:PQoidValue() can return InvalidOid, so this appears like a legitimate use to me.
Feelfree to correct me though, I have not used the C fe before.
