Yes, we could do that. And those libs could possibly just be the
symlinks (or even just a Provides: header).

I tried going from 4.1 (the earliest one I have installation CD's for)
to pre-7.0 once. I don't recommend it.

Good. Let me know what you decide, if you don't mind.

And unfortunately PHP and other PostgreSQL clients also link against the
specific libpq version. This has caused pain for those installing the
PHP stuff from RPM which was linked against a RedHat 6.2 box with
PostgreSQL 6.5.3 installed -- onto a RedHat 6.2 box with PostgreSQL
7.0.2 installed. There is a failed dependency on libpq.so.2.0 -- even
though libpq.so.2.1 is there.
A symlink works around the problem, if the symlink is part of the RPM so
that it gets in the rpm dep database. Of course, this only causes
problems with RedHat 6.2 and earlier, as RH 7's PHP stuff was built
against 7.0.2 to start with. But, 7.1 with libpq.so.2.2 will cause
similar dep failures for PHP packages built against 7.0.2.
