Hm.  Since we force people to recompile extensions for new major versions
anyway, maybe it'd be all right.  I'm sure there is *somebody* out there
who will have to adjust their build scripts, but it does seem like it
shouldn't be much worse than other routine API changes.

[ thinks for a bit... ]  Might be worth double-checking that pg_upgrade
doesn't get confused in a cross-version upgrade.  A quick grep doesn't
find that it refers to DLSUFFIX anywhere, but it definitely does pay
attention to extensions' shared library names.
