[pmp-p]

"xml2" (pgxml) / "uuid-ossp" / "pgcrypto" can be built when sdk 3.1.65.5bi is available
uuid-ossp rely on a full pg rebuild with ossp-uid selected.

"intarray" is available under name "_int.tar.gz"

"intagg" is marked obsolete in its control file, and has no shared object so python extension packer does not know how to handle it.

but lgtm for now !
