Stabilize plancache test against on-access VM setting Since b46e1e54d07 allowed setting the VM on-access and 378a21618 set pd_prune_xid on INSERT, the testing of generic/custom plans in src/test/regress/sql/plancache.sql was destabilized.
One of the queries of test_mode could have set the pages all-visible and if autovacuum/autoanalyze ran and updated pg_class.relallvisible, it would affect whether we got an index-only or sequential scan. Preclude this by disabling autovacuum and autoanalyze for test_mode and carefully sequencing when ANALYZE is run.
