Re: Deleting prepared statements from libpq.

now it works.

should it be "if (PQresultStatus(res) == PGRES_FATAL_ERROR)" ?

Similarly the following line should also change?

> res = PQdescribePrepared(conn, "select_one");
> if (PQresultStatus(res) != PGRES_FATAL_ERROR)
> pg_fatal("expected FATAL_ERROR, got %s", PQresStatus(PQresultStatus(res)));



typo, unnecessary "portal." in the following sentence?
   "portalName can be "" or NULL to reference the unnamed portal, it is
fine if no portal exists with this name. portal. On success, a PGresult
with status PGRES_COMMAND_OK is returned."

"Also, although there is no libpq function for deleting a prepared
statement, the SQL DEALLOCATE statement can be used for that purpose."
Now the PQclosePrepared has the same use as DEALLOCATE, maybe the above
sentence should be changed?
