Hi! Thank you.

This script creates cluster copy in every night. So this should be done automatically. I have little experience with Linux. Can you provide example, how it should it be done using sed or other tool. There is also second user named dbandmin whose password cannot changed also. It would be best if CREATE ROLE and ALTER ROLE clauses for postgres and dbadmin users are removed for file. Or if this is not reasonable, same passwords or different role names can used in both clusters. Also I dont understand why GRANTED BY clauses appear in file. This looks like noice. GRANT documentation https://www.postgresql.org/docs/current/sql-grant.html does not contain GRANTED BY clause. It looks like pg_dumpall generates undocumented clause. Andrus.
