pg_upgrade question

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
