Make GIN regression test stable.
Commit 7f46eaf added the regression test which checks that
gin_clean_pending_list() cleans up the GIN pending list and returns >0.
This usually works fine. But if autovacuum comes along and cleans
the list before gin_clean_pending_list() starts, the function may
return 0, and then the regression test may fail.
To fix the problem, this commit disables autovacuum on the target
index of gin_clean_pending_list() by setting autovacuum_enabled
reloption to off when creating the table.
Also this commit sets gin_pending_list_limit reloption to 4MB on
the target index. Otherwise when running "make installcheck" with
small gin_pending_list_limit GUC, insertions of data may trigger
the cleanup of pending list before gin_clean_pending_list() starts
and the function may return 0. This could cause the regression test
to fail.
