In version 7.3, the support for the pgsql V 6.2 FE/BE protocol was
removed. So, what you might want to do is look for which versions of
the FE/BE protocol have been added over time. Basically, the server
will fall back to whatever version it has to in order to communicate,
and after V 7.3, the oldest clients, the ones written with the release
of 6.2 would now fail. So, the chart, for versions 6.3 and up would be
kind boring on a Yes No basis.
So, I'd toss in the FE/BE versions.
I don't have that real handy, but Tom or Bruce probably know (mostly)
all that off the top of their heads.
