Melanie Plageman b93961add9 Stabilize btree_gist test against on-access VM setting
The btree_gist enum test expects a bitmap heap scan. Since 0172721d14
enabled setting the VM during on-access pruning and 502167cfe set
pd_prune_xid on INSERT, scans of enumtmp may set pages all-visible.
If autovacuum or autoanalyze then updates pg_class.relallvisible, the
planner could choose an index-only scan instead.

Make the enumtmp a temp table to exclude it from autovacuum/autoanalyze.
