This sounds like a little bit unfair argument. The libpq documentation
is pretty sloppy for the error case for other PQ* as well. For
example, look at the PQdb document:

PQdb
Returns the database name of the connection.
char *PQdb(const PGconn *conn);

This says nothing about when the connection is bad. Reality is PQdb
returns NULL in the case. But are we allowed to change PQdb returns
say, "template1" when the connection is bad because the doc says
nothing about error case?
