I'm fooling around with Guillaume Lelarge's patch to make psql's \d
commands work with older server versions. The patch as submitted
works with servers back to 7.4 (modulo a small bug or two). I tried
to see what it'd take to make it work with 7.3. I count about a dozen
trivial diffs and about three nontrivial ones --- nontrivial meaning
I didn't see a simple fix right away. This seems a bit more work than
is justified for a server version that the community has officially
dropped support for, but I wonder if anyone feels hot about it?
Pre-7.3 server versions seem entirely out of the realm of reason because
they lack schema support, meaning all of those "pg_catalog." prefixes
break, not to mention the joins to pg_namespace and the "schema" output
columns. So it's just 7.3 that's worth debating, I think.
