Hi Fabio,
sorry to bother you again, its still failing with stopping both server (8.4 and 9.4)
-bash-4.2$ /opt/rh/rh-postgresql94/root/usr/bin/pg_upgrade --old-bindir=/usr/bin --new-bindir=/opt/rh/rh-postgresql94/root/usr/bin --old-datadir=$OLDCLUSTER --new-datadir=$NEWCLUSTER
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/ericsson/esm-data/postgresql-data" -o "-p 50432 -c autovacuum=off -c autovacuum_freeze_max_age=2000000000 -c listen_addresses='' -c unix_socket_permissions=0700" start
Failure, exiting
With Best Regards

Subject: Re: pg_upgrade help
Hi,
i was too fast in reply (and perhaps i should drink my morning coffee
before replying), I will try to be more detailed:
both servers should be able to run at the moment you run pg_upgrade,
that means the 2 servers should have been correctly stopped in advance,
should have their configuration files, and new cluster initialized too.
Then, as Sergei highlights here below, pg_upgrade will take care of the
upgrade process, starting the servers.
Here there is a step by step guide, i considered my best ally when it
was time to upgrade:
https://www.postgresql.org/docs/9.4/static/pgupgrade.html
note point 7:
'stop both servers'
About the port the servers will run on, at point 9 there is some
clarification:
' pg_upgrade defaults to running servers on port 50432 to avoid
unintended client connections. You can use the same port number for both
clusters when doing an upgrade because the old and new clusters will not
be running at the same time. However, when checking an old running
server, the old and new port numbers must be different.'
Hope it helps,
Fabio Pardi
