I thought that might prick your ears up. Yes, I'm looking at just how
horrible it might be to implement SQL schemas. As it turns out, I think
Tom is right, and I can just use a regular system table. I've got that
working, and some of the gammar modified to accept the schema.table
notation: now I'm working from both ends on all the places in between
that need to know about the schema. Vadim's work replacing relnames with
relfilenode helps to some extent.

I'm taking the simplistic approach of adding the schema name wherever
the relname is currently used, in parallel, and introducing a new global,
the current default schema.

As I said in my first note, I'm trying this out, regardless if it's the
best way to implement the feature (why is it that I only seem to find
time to work on new stuff in pgsql when we're in beta?) We can debate a
better implementation after I have roughly working code, or have given
up on it as a bad idea.

As it happens, my pgsql time this week is taken up by another task, so I
won't be working on this until the weekend, at the earliest.
