At the moment I am working on join *syntax*, so my changes are
isolated to gram.y, analyze.c, parse_clause.c, and parse_target.c.
Don't wait for me; I'll bet that we don't collide much, and if we do I
don't mind doing the merge.

Sometime later, once I understand the syntax and have it coded for
inner joins, I'll want to start modifying the parser and planner to
handle outer joins. At that point, I'll be asking for help and advice,
and look forward to your input. But I'm not there yet.

I'm hoping to have some updates committed in a week or so, but things
have been going very slowly with little time to work on this :(
