implemented experimental "consistent_publisher" option:
/!\ pgsql schema needs to be updated /!\
New "consistent_publisher" option has been implemented to allow node owners + admins to
modify an item while preserving the original publisher. This way, original publisher can
still edit the item.
In addition to `consistent_publisher`, `max_items` has been added to PGQSL schema to
prepare for future implementation.
