TODO marked as done:

* Add schema, cast, and conversion backslash commands to psql

I had to create a new publically available function,
pg_conversion_is_visible, as it seemed to be missing from the catalogs.
This required me to do no small amount of hacking around in namespace.c

I have updated the \? help and sgml docs.

\dc - list conversions [PATTERN]
\dC - list casts
\dn list schemas

I didn't support patterns with casts as there's nothing obvious to match
against.

Catalog version incremented --- initdb required.
