Here is a patch to create unique GiST indexes. It is not really
finished yet, but I thought I would share. It is intended to address
the bug discussed at [1], where calling pg_get_indexdef on a WITHOUT
OVERLAPS constraint generates SQL that Postgres refuses to run. I
realized after sending that email that the thread is on pgsql-bugs,
but I think it belongs on pgsql-hackers now (for one reason, so I can
create a commitfest entry). Please see my notes at that link, and
apologies for the extra noise.
