Well, what we *really* need is a convincing argument that it's worth
taking some risk for.  I find that not obvious.  You can pipe the output
of pg_dump into your-choice-of-compressor, for example, and that gets
you the ability to spread the work across multiple CPUs in addition to
eliminating legal risk to the PG project.  And in any case the general
impression seems to be that the main dump-speed bottleneck is on the
backend side not in pg_dump's compression.
