Say I'm writing an extension X, and I want to process data values from
another extension that creates type Y (e.g. an hstore), what's the best
way to determine the Oid of type Y in my module X code? SPI code that
runs "select 'something'::Y" and then examines the oid in SPI_tuptable?
Or do we have a utility function I have missed that, given a type name
and the current search path will give me back the type Oid?
cheers
