You can do it already. See PQsendQuery and PQgetResult.
mentions this specifically:
PQexec can return only one PGresult structure. If the submitted
command string contains multiple SQL
commands, all but the last PGresult are discarded by PQexec.
There is a lot of other cruft here to allow nonblocking interaction with
the server, but if all you care about is multiple commands sent in a
single string, you only need
while ((res = PQgetResult(...)))
