Re: How to restore roles without changing postgres password

pg_dumpall creates an SQL file which is just a simple text file

you can then edit sql removing postgres user from the file

This can be automated in a script that searches the generated sql file for
the postgres user replacing it with a blank/empty line or adds -- to the
bringing of the line which comments it out.
