Why don't we just add an option to pg_dump --use-compress-program, just
like tar and then people can use their "compression algorithm of the
week" and we don't need to care about the licence or anything.
It's not like the case of TOAST where it actually needs to be builtin.
Tar doesn't have any compression builtin, yet you don't see many
uncompressed tar files...
Have a nice day,
