Since there's no existing GUC category that fits to vacuum_truncate,
I'm fine with adding a new category like "Vacuuming" and placing
vacuum_truncate there.
However, if we do this, ISTM that the new category should also be added to
guc_tables.h, and vacuum_truncate should be assigned to it in guc_tables.c.
Additionally, the documentation should be updated to include
the new category, with vacuum_truncate placed under it. Thought?
