What? The default length limit has been 31 characters for a long time,
certainly long before 6.5.*.

7.0 has a new behavior of *telling* you that it's truncating overlength
identifiers, but the system has always truncated 'em.

If you're simply complaining about the fact that it emits a notice,
I agree with you 100%: that notice is one of the most nonstandard,
useless, annoying bits of pointless pedantry I've seen in many years.
I argued against it to start with but was outvoted. Maybe we can have
a revote now that people have had some practical experience with it:
who still thinks it's a good idea?

You could recompile with a larger NAMEDATALEN, but unless you did so in
your 6.5.* installation, that's not what's bugging you. Look for the
elog(NOTICE,...) call in src/backend/parser/scan.l and dike that out,
instead.
