Edit the
pg_hba.conf(https://www.postgresql.org/docs/15/auth-pg-hba-conf.html) so
that the first local line is set to trust as in the 'Example 21.1.
Example pg_hba.conf Entries' at the bottom of the file. It may already
be set that way.

In either case when you connect do not use a host setting e.g. do not do
host=localhost. This will ensure you are connecting to the local socket
instead and will be using the trust authentication method and not a
password. Once you are in you can alter the postgres user to have a
proper password.
