Good afternoon,
I am hoping to use pg_upgrade with the link option to upgrade from 9.2 to
9.4.
We run redhat linux
This is the current configuration:
There is one set of binaries:
/usr/local/postgresql-9.2.5 >>> upgrade to >>>
/usr/local/postgresql-9.4.8.
However there are *three *sets of data clusters. All on different disks -
same file structure. They are on the same physical machine but referenced
by different i/ps and have to be referenced to different hosts:
first data cluster:
/postgres_data/legacy/PSQL_92 >> upgrade to >>
/postgres_data/legacy/PSQL_94
to reference this at the command line within linux
psql -U <<rolename?>> << database>> -h prod-legacy-psql.server.int
second data cluster
/postgres_data/prime/PSQL_92 >> upgrade to>> /postgres_data/prime/PSQL_94
to reference this at the command line within linux
psql -U <<rolename?>> << database>> -h prod-prime-psql.server.int
third data cluster:
/postgres_data/autoscheduler/PSQL_92 >> upgrade to>>
/postgres_data/autoscheduler/PSQL_94
to reference this at the command line within linux
psql -U <<rolename?>> << database>> -h prod-autoscheduler-psql.
server.int
Is this possible using pg_upgrade? From the documentation it looks like
there is a one-to-one correlation between the binaries and the data cluster
- I don't see a 'multiple' option.
Thanks for your time.

As far as pg_upgrade is concerned, you'd just run it three times, once per
data cluster.
If you're trying to use it through some distro-provided wrapper script,
it's possible that that would be difficult, but the paths you mention
sound pretty homebrew so I'm guessing that that's not a problem.

Sorry late to reply, but in your case Mark, you would run pg_upgrade
three times, once for each data directory, but use the same binaries
directory each time --- I think that is what you were asking below:
