In this post:

https://www.postgresql.org/message-id/793E4164-90E9-41F0-B74C-129E1DB76408%40clover.co

it worked. Though in that case pg_upgrade was not run before you ran:

/usr/pgsql-13/bin/pg_ctl -D /var/lib/pgsql/13/data/ -l logfile start

Can you start with clean initdb and then run above command to see if you
can connect. Then run:

/usr/pgsql-13/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D
"/var/lib/pgsql/13/data" -o "-p 5432 -b -c synchronous_commit=off -c
fsync=off -c full_page_writes=off -c vacuum_defer_cleanup_age=0 -c
listen_addresses='' -c unix_socket_permissions=0700 -c
unix_socket_directories='/var/lib/pgsql'" start

and see if you can connect. Leave pg_upgrade out of the mix to see if it
is indeed the issue.
