Many years ago I needed to write a program that needed to be able to fetch a list of tables in the DB, and then a list
ofattributes for each table. It took me at least a full day and I almost gave up and abandoned PostgreSQL as a result.
Ithink calling this duplicate functionality is ridiculous.  Sure, it's possible. In fact, it's very easy.
