Fix typo in freeze_table_age implementation
The original code used freeze_min_age instead of freeze_table_age. The main consequence of this mistake is that lowering freeze_min_age would cause full-table scans to occur much more frequently, which causes serious issues because the number of writes required is much larger. That feature (freeze_min_age) is supposed to affect only how soon tuples are frozen; some pages should still be skipped due to the visibility map. Backpatch to 8.4, where the freeze_table_age feature was introduced. Report and patch from Andres Freund
