My question was limited to it's use in pg_dump; rather than basing
pg_dump's compression bahaviour on configure, base it on it's runtime
environment. But my guess is you still would be inclined, rather strongly,
against it.

This begs the obvious question: should pg_dump be using Jan's compression
code? In all cases/when zlib is not available?
