How to extract table names and column names from plpgsql

Question

On the same line as the @Dylan Hogg (user:249597) you mentioned the sql-app.infocruncher.com hosted library is there one for plpgsql? Would highly help GP migration tasks.

Basically I have the GP function script from which I'd like to get the inventory of table and column names. Ideally the Column data types as well.
