Interesting thread(s)!
What I didn't see discussed was the possibility of making a server
and/or session option, where we could elect to turn-off the old behavior
(PG specific behavior) and enable the standard/shorthand syntax. Users
need a migration path.
I personally cant ever see using those PGisms/features and would choose
to enable the standard mode. I think I'd have fewer compatibility problems.
