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.
