You should define "locked" more carefully: exactly what behavior are you
seeing that you don't like?
If it's a matter of whether VACUUM removes rows or not, that's expected:
open-transaction bookkeeping is done across the whole cluster. (This is
not something simple to change, since we may have to consider
transaction IDs in shared catalogs.)
