Zoltan's original complaint was real, and he bumped into it in 9.1 and
9.0. There are few people using these macros in third party code, so I
doubt we'll hear many reports either way.
The memory leak should be fixed now, and I don't foresee any new issues
cropping up, so I'm not inclined to revert it anymore. Within PostgreSQL
itself, I couldn't find any more references to these macros.
If we do revert, I think we should still leave the DatumGetInetPP()
macro in place. It would be identical to DatumGetInetP(), neither would
unpack, but DatumGetInetPP() would be the preferred macro to use for
that purpose.
