Thanks Fabio for instant reply.
I now started 8.4 with 50432 and 9.4 with
default port but still its failing ...Can you please suggest what is wrong
?
-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
*failure*
Consult the last few lines of "pg_upgrade_server.log"
for
the probable cause of the failure.
There seems to be a postmaster servicing
the old cluster.
Please shutdown that postmaster and try again.
Failure, exiting

Re: pg_upgrade
help
Hi,
please avoid crossposting to multiple mailing lists.
You need to run both versions of the database, the old and the new.
They need to run on different ports (note that it is impossible to run
2
different processes on the same port, that's not a postgresql thing)
