quote_ident is a good bit more conservative than the core lexer
about what is an "identifier character" --- it considers all
non-ASCII characters as requiring quoting, too.
For typical uses of quote_ident, I think this is good future-proofing:
it makes it very much less likely that something quote_ident decides
not to quote would be rejected by some future PG version (not to mention
non-PG SQL databases). So I'm not really in a hurry to change the code.
Maybe we should tweak the docs a bit.
