I haven't fully kept track of which other packages do support multiple
versions. But at least both yum.postgresql.org and apt.postgresql.org
support multiple *postgresql* versions. Meaning that if they *do*
support only one postgis version, there might be a problem if you drop
support for older versions of pg - since older versions of postgis
don't necessarily work with the newer versions of pg.

I really don't know enough details to comment more clearly though, but
I've heard of complaints elsewhere around this so I wanted to make
sure it's brought up. I don't know if the guys working on those
packagings are actually on either of the two lists, so I'd suggest
throwing a quick email to their respective lists and ask (they're both
on http://www.postgresql.org/community/lists/).

Actually, it would probably be a good thing in general if we could get
the packagers to build against the development snapshots as well - to
find bugs quicker, and get them taken care of before it hits release.
I'm not sure how feasible it is, but it would be good in general :)

And yes - it's definitely a good thing to get it done early. If it's
going to be desupported, the earlier people find out, the better!
