The important bits start here, I think.
Distilled:
1. Do you have an existing VM infrastructure, like VMware?
2a. Do you frequently create new PG instances?
2b. Do you have hundreds of PG instances?
For me, the answers are "yes" and "no,no".
I've got a "design document" and common config files in a shared directory. Need a new PG server? I give a standard list of mount points and port numbers to the VM build team, and they come back with a server that has RHEL installed, and ports open. "yum install" a set of RPMs from PGDG. Five minutes later, I sudo to postgres, cp config file templates and run some sed commands. Up comes PG!
Patching happens every three months; yum and bash scripts which I've developed over time make that pretty darned fast and painless.
Thus, PG containers are of no use to us. Lots of application containers, but that's outside my domain.
