Better psql tab-completion support for schemas and tables

(oops, this time with -c, thanks Alvaro)

Full support for all schema and table name combinations when
getting a list of attributes. All of the following will now work:

select * from information_schema.columns where <tab>
select * from foo where <tab>
select * from "user" where <tab>
select * from "foo" where <tab>
select * from "Uppercase".lower where <tab>
select * from "gtsm.com"."foo.Bar" where <tab>
select * from "GTSM.com".foo where <tab>

Also applies to other places that get lists of columns: insert into,
alter table, create index, etc.

Applied with minor revisions. I noticed while testing this that
although you fixed it for the case of the user having unnecessarily
quoted the preceding name, for example given a table foo,

update "foo" set <tab>

it's still not bright about letting you complete such an entry in the
first place -- try

update "f<tab>

That doesn't invalidate this patch, but there's still more work to do
on the completion queries.
