Schema-qualify unnest() in ALTER DATABASE ... RESET

Browse Source 
Commit 9df8727c5067 failed to schema-quality the unnest() call in the
query used to list the variables in ALTER DATABASE ... RESET. If there's
another unnest() function in the search_path, this could cause either
failures, or even security issues (when the tab-completion gets used by
privileged accounts).

Report and fix by Dagfinn Ilmari Mannsåker. Backpatch to 18, same as
9df8727c5067.
