Hi hackers,

These two patches are split out from my earlier thread about improving
tab completion for varous RESET forms
(https://postgr.es/m/87bjqwwtic.fsf@wibble.ilmari.org), so that the bug
fixes can be tracked as an open item for v18.

Commits 9df8727c5067 and c407d5426b87 added tab completion for ALTER
DATABASE ... RESET and ALTER ROLE/USER ... RESET, respectively, but
they're both differently buggy.  The query for the DATABASE form
neglected to schema-qualify the unnest() call, and the query for the
ROLE/USER form shows all possible variables once you start typing a
variable name, not just the ones that are set on the role.  The attached
patches fix both.
