I think this was already discussed here. It turns out that a specific
exception for PG wouldn't be acceptable because of the multiple
commercial derivates. LZO would have to become BSD, which presumably
the author just doesn't want to do.
Maybe we could have a --enable-lzo switch similar to what we do with
readline. Of course, a non-LZO-enabled build would not be able to read
a dump from such a build. (We could also consider LZO for TOAST
compression).
