Re: Get TupleDesc for extension-defined types

Correct me if I'm wrong,

but for an extension that defines composite types,

there's currently no easy way to get a TupleDesc, even for its own types.

Something like 

TupleDesc get_extension_type_tupledesc(const char *extname, const char *typname)

Here's a routine I've stolen borrowed from pramsey's code and have been using ever since.

Could this be exposed in extension.h ? (probably without the version check)
