Hi,

I have 10+ postgresql clusters (v 9.6) running on one machine - each having
their own data directory and port. They all share same binaries though, and
this is now giving me some headache.. I cannot shutdown all clusters at the
same time, so upgrading them is quite impossible.

I know that running several versions of postgres is possible on one machine
- I suppose this would also work out with same version running on different
locations, like /db1/PostgreSQL/10, /db2/PostgreSQL/10.. etc..? Has anyone
any experience with this kind of problem?

All help and ideas appreciated! :-)

Thanks,
Erika
