I don't see any real reason why we couldn't document this one. It
returns OIDs, but that's the name of the game if you're doing anything
non-trivial with PostgreSQL system catalogs. Off-hand I'm not quite
sure which section of the documentation would be appropriate, though.
It looks like the functions we provide are mostly documented in
chapter 9, Functions and Operators. Section 9.23 on "System
Information Functions" seems like it's probably the closest fit...
