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.

Hi!
How to create backup script which restores all roles and role memberships
from other server without changing postgres user password.
I tried shell script
PGHOST=example.com
PGUSER=postgres
PGPASSWORD=mypass
export PGHOST PGPASSWORD PGUSER
pg_dumpall --roles-only --file=globals.sql
psql -f globals.sql postgres
but this changes user postgres password also.
How to restore roles so that postgres user password is not changed on
restore.
Script runs on Debian 10 with Postgres 12
Server from where it reads users runs on Debian Squeeze with Postgres 9.1
