I've been wondering if we should stop thinking that each contrib's
module version is the same as the backend version. What if we declare
them all 1.0.0 for the 9.1 release, and increment the version manually
each time there's a change? So a module that stays unchanged for 9.2
would still be 1.0.0. (The .so file would still need to be recompiled
for the new server version, because of PG_MODULE_MAGIC.)
In that case, having hand-maintained version numbers in control or
wherever is not so much of a problem; the committer that touches the
module needs to ensure that the version number is incremented too.
