I'm a bit skeptical about this - at least in V12 there's only two GUCs
with 'maintenance' in the name: maintenance_work_mem and
max_parallel_maintenance_workers. Both are used for utility commands and
do not apply to regular user queries while (AFAICT) your proposal is not
limited to utility commands. So I think if you name it
'maintenance'-something, people will assume it only involves VACUUM or
so.
