Worse still, doing a cluster of most of the tables and vacuum full analyze

Why are you doing a vacuum full? That command is not meant to be used except in the most unusual of circumstances, as it causes bloat to indexes.

If you have run a cluster command, then running vacuum full will make the table and index layout worse, not better.
