This remoinded me of a question I wanted to ask Unix people: other OSs I
use allow for dynamic linking, at runtime and in code, against shared
libraries, and I know Unix must allow this. The places where zlib is used
are pretty limited, so it might be worth considering doing the 'HAVE_ZLIB'
kinds of checks at runtime. Then one binary fits all...

Is this hard or easy - at least on machines with a libz.so?

Is it worth doing?

I guess the alternative on rpm is to create both: pg_dump.zlib and
pg_dump.nozlib, and install the right one?
