I disagree. It's not just about testing. A customer running a production site 
will be much more comfortable knowing that he can have both major versions 
installed at the same time, and only do away with the old one when he's safe 
knowing the import into the new one worked fine.

I should say I did not know about the existence of PG_SUBPREFIX at all until 
this thread, and have been cursing at CONFLICTs all the time, wishing 
PostgreSQL support in pkgsrc had been writen the OpenSolaris way (i.e. each 
version having its own installation prefix + storage data directory). At the 
same time knowing the significant problems raised by such approach of course… ;)
