Ok. With the data from my 9-4, i.e /db/pgsql/data, and with
postgresql.service stopped.
# postgresql-setup --upgrade
* Upgrading database.
ERROR: pg_upgrade tool failed
ERROR: Upgrade failed.
* See /var/lib/pgsql/upgrade_postgresql.log for details.
# cat /var/lib/pgsql/upgrade_postgresql.log
*failure*
Consult the last few lines of "pg_upgrade_server.log" for
the probable cause of the failure.
connection to database failed: could not connect to server: No such
file or directory
Is the server running locally and accepting
connections on Unix domain socket "/home/postgres/.s.PGSQL.5432"?
could not connect to old postmaster started with the command:
"/usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl" -w -l
"pg_upgrade_server.log" -D "/db/pgsql/data-old" -o "-p 5432 -b -c
listen_addresses='' -c unix_socket_permissions=0700 -c
unix_socket_directories='/home/postgres'" start
As you can see, postgres can't find the socket
