PQfformat() applied to a column of a result indicates whether it's text
or binary.
When the query is run through PQexec(), my understanding is that
results will always be in text format except if specified otherwise at
the SQL level. That would be the case for a FETCH from a BINARY CURSOR.
I'm not sure if there is any other case, BTW, anyone knows?
