Обсуждение: multiple postgres instances from RPM install
I am getting ready to set up 2 postgres instances, but I’m somewhat new to postgres. I’ve used RPM to list out all the files that are installed, and I think I’ve isolated all the executables of which I need to make separate copies, but I was hoping for some confirmation. I heard the exact files that need copying are listed in a thread somewhere in the archives, but I can’t seem to find it. Could someone please point me to it?
The motivation behind this is having 2 distinct SELinux policies for 2 separate users with their own separate databases.
Thanks,
Tom

After consulting with a teammate, I've found out that they'd have no problem simply doing 2 separate makes. In fact, I'm glad. It's makes much better sense.

That is not an option. We're currently doing that. The customer wants separate installations of postgres, mostly for security reasons. Admin is divvied up between 4-5 "admin" user accounts on the system because there are several user roles in our product's community. Separate installations allow one "admin" user to control everything involved with the database (including the postmaster executables) for one application and another "admin" user to control everything involved with a the database for a different application.
