Well, I for one LOVE $$ quoting in the newer versions of pgsql.
Having statements with ''''''''value'''''''' in the, was downright
annoying in 7.4...
I think the real issue with all the pl languages is the variations in
quality of implementations out there. And some don't always make it
to the next release, or if they do they lag behind. I believe plsh
was quite late to show up for 8.0 back in the day... If you're
relying on a particular pl{lang} you kinda want to check to see if
it's still working on the latest pg version before upgrading.
