The potential for misusing the switch is only one small part of the
argument; the larger part is that this has been done in the wrong way
and will cost performance unnecessarily. The fact that it's ready
now is not something that I think should drive our choices.

I believe that it would be possible to make the needed core-server
changes in time for 8.3, and then to work on compress/decompress
on its own time scale and publish it on pgfoundry; with the hope
that it would be merged to contrib or core in 8.4. Frankly the
compress/decompress code needs work anyway before it could be
merged (eg, I noted a distinct lack of I/O error checking).
