I'm not a big fan of doing it for this specific item, though it's
technically an API breakage (which means we should actually have
libpq2-dev packages, make everything that build-deps on libpq-dev
update to build-dep on libpq2-dev, have libpq6, etc..). If there are
other backwards-incompatible things we wish to do, then I agree that
it'd be good to do them all at the same time (perhaps in conjunction
with 10.0...). This is the part where I wish we had been keeping an
updated list of things we want to change (like on the wiki..).
It's certainly not a fun transistion to go through. I also wonder if
we're going to need to worry about what happens when libpq5 and libpq6
end up linked into the same running application. I don't think we
have any symbol versioning or anything to address that risk in place..
Thanks,
Stephen
