Re: Multiple postgresql clusters with same version and separate binaries

I did say you need to run with different binaries for different versions:

To put it simply: you cannot run different major versions of PostgreSQL
with the same binaries.

So when I subsequently said the following it was in that context.

The 3rd one is separate binary locations for each PG cluster instance
running on the same host.
