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...
tar compresses/decompresses the whole archive via a single pipe. pg_dump compresses individual data members. If the compression isn't builtin it will make life much more difficult, and probably make parallel restore as well as some other operations well nigh impossible.
