Re: BUG #3015: libpq: PQftype() on a lo type result column returns Oid of type oid instead of Oid of type lo.

Thanks Tom. I used to rely on the PQftype() to determine if the OIDs
stored in that result field are pointing to large objects or not. If
they are large objects, I used to fetch them using lo_* API.
Now since PQftype() returns type oid for type lo columns, how will I
identify if a result column contains large objects or not? One way I can
think of is to use PQftable() and PQftablecol() and then query the type
of the table column from pg_attribute. Would this be the correct way? Is
there a better and easier way to identify the data to be lo?

Thanking you in advance.

This is an expected change: type "lo" isn't an independent datatype
anymore, just a domain over OID.
