Well, I was thinking about it and came to the conclusion that we are
neither taking heavy locks nor explicitly opening a transaction and
therefore we can avoid changing them.
But maybe you are right, having them set to the safe value shouldn't hurt.

I don't think we can use the same wrapper for run_simple_query() and
for places where we call a SET, because PQresultStatus() returns
PGRES_TUPLES_OK and PGRES_COMMAND_OK respectively.
Passing expected ExecStatusType to the wrapper for comparison is
looking a bit ugly to me.
