I've been looking at compatibility with 8.3 prior to building a demo of 
the new style windows installer for PostgreSQL that we're planning. I 
see that CVS head has an update to use VARATT_SIZEP_DEPRECATED instead 
of VARATT_SIZEP, however this change is obsolete already following 
Greg's recent work minimising the on disk size of various datatypes.

Before I spend any time on this, is anyone else working on 8.3 
compatibility?

I'd also like to back port this to 1.2.x so we can release a build with 
PostgreSQL 8.3. Any objections?

Regards, Dave.
