to help make an vacant databases without any nearby additions, duplicate from template0 not template1, for example:
could be a connection string. If that's so, link string parameters will override any conflicting command line possibilities.
Requesting special locks on database objects when jogging a parallel dump could induce the dump to fall short. The explanation would be that the pg_dump chief process requests shared locks (obtain SHARE) within the objects which the worker procedures will dump later if you want to make sure that no one deletes them and can make them go away although the dump is running. If A different customer then requests an distinctive lock on the table, that lock will not be granted but might be queued awaiting the shared lock in the chief process to be launched.
