I am struggling to learn libpq.
for some reason, I could not get an INSERT to produce an Oid. actually, what I am looking for, is to get the ID of the last record inserted or to verify that I inserted a record successfully. I think you use PQresultStatus() for that.(?)
Isn't PQoidValue() for getting the last INSERT id? or am I misunderstanding it?
I just figured out how to set the start id of a BIGSERIAL to 1000.
SAMPLE OUTPUT:

pgr = PQexec(pgc,querystr);
if (PGRES_COMMAND_OK!=PQresultStatus(pgr)) {
printf("INSERT result is not OK\n");
} else {
Oid oid = PQoidValue(pgr);
if (0 == oid) {
printf("ERROR: INSERT operation failed!\n");
}
}
