Yes, Ubuntu/Debian make it easy to run multiple versions/clusters at 
once. I don't think they even use the alternatives system (but I could 
be wrong). For building/installing the extension, the only important 
part AIUI is getting pg_config to point at the right files. My own 
approach has always been to hack the bash code to accept a PGCLUSTER 
envvar, as in that Stack Overflow answer. Someone here might have a 
better approach though.
