Hi all,
Some time ago we added [1] the infrastructure to allow different lock
levels for relation options.
So per discussion [2] the attached patch reduce lock levels down to
ShareUpdateExclusiveLock for:
- fastupdate
- fillfactor
- gin_pending_list_limit
- seq_page_cost
- random_page_cost
- n_distinct
- n_distinct_inherited
- buffering
Att,
