با سلام دوستان من تو روند آپگرید به این خطا میخورم کسی میتونه کمک کنه ؟

*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 "/var/run/postgresql/.s.PGSQL.50432"?


could not connect to old postmaster started with the command:
"/usr/bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "/var/lib/pgsql/data/" -o "-p 50432 -c autovacuum=off -c autovacuum_freeze_max_age=2000000000 -c listen_addresses='' -c unix_socket_permissions=0700" start
Failure, exiting
