Fix for PostgreSQL enums not in the schema search path (RT#123234)
Dagfinn Ilmari Mannsåker [Tue, 10 Oct 2017 12:47:26 +0000 (13:47 +0100)]
Cast the data type name to regtype instead of comparing it directly to
pg_catalog.pg_type.typname, so that schema-qualified type names are
interpreted correctly.

In passing, change the queries to use $data_type instead of
$info->{data_type}, for consistency.
