Dramatically increase OID type matching.

We were never finding some OID types in the type_map and this
is at some point in 7.0 they started saving ones which can be
namespace-specific in a quoted namespace way "ns"."my_type".

Hacked this into our code but I am missing something.  Perhaps
JDBC resultset processing can do the right thing here.
