Technically, you need to look and see what schema something is in. Take
a look at how the newsysviews project on pgFoundry does it.

The general consensus seems to be that the things in pg_catalog should
provide a minimalist view. The newsysviews project was created in the
hope that we could get a more human-friendly version of that data put
into core, but it's been neglected for a while now (for one thing, there
was desire to make it look more like information_schema).
