I don't particularly like the explicit comparisons using LIKE, but we
can't really do better as we only have pg_my_temp_schema(),
pg_is_other_temp_schema() right now. I was tempted to just add
pg_is_temp_schema() and pg_is_toast_schema(), but we couldn't rely on
them for now anyway due to cross version compatibility.
We really should add those functions independently of this though.
I'm also not really happy with the fact that we only complete a single
search_path item. But it's not easy to do better and when looking around
other places (e.g. DROP TABLE) don't support it either.
I've thought about adding "$user" to the set of completed things as
Fujii wondered about it, but it turns out completions containing $ don't
work really great because $ is part of WORD_BREAKS.
E.g. check out what happens if you do
CREATE TABLE "foo$01"();
CREATE TABLE "foo$02"();
DROP TABLE "foo$<tab>
which means that a single schema that requires quoting will break
completion of "$user".
Pushed.
