It really would be nice to address that. (FWIW A few years ago I had a
mostly-working experiment-grade patch for the ports tree that could
install and run multiple versions in parallel, and the bones of a port
of the Debian wrapper scripts and cluster control tools so you can
list, start, stop, clone clusters etc, but I ran out of steam while
contemplating the squillions of other packages that interact with
PostgreSQL... happy to share the starter bits and pieces I have
off-list if anyone is interested...). But in this particular case it
significantly reduces the search area for the problem, so that's a
useful deficiency!
