Add back vacuum_cleanup_index_scale_factor parameter.
Peter Geoghegan <pg@bowt.ie>
Add back vacuum_cleanup_index_scale_factor parameter. Commit 9f3665fb removed the vacuum_cleanup_index_scale_factor storage parameter. However, that creates dump/reload hazards when moving across major versions. Add back the vacuum_cleanup_index_scale_factor parameter (though not the GUC of the same name) purely to avoid problems when using tools like pg_upgrade. The parameter remains disabled and undocumented. No backpatch to Postgres 13, since vacuum_cleanup_index_scale_factor was only disabled by REL_13_STABLE's version of master branch commit 9f3665fb in the first place -- the parameter already looks like this on REL_13_STABLE.
