Perhaps this should this be [[:alpha:]][[:word:]]*? According to https://ruby-doc.org/core-2.1.1/Regexp.html , \w only matches ASCII characters. I'm not sure if PL/pgSQL allows unicode identifiers, but I don't remember why I matched non-ASCII chars here in the first place!

If Unicode is not allowed, this a-z\w_0-9 could probably be simplified to \w, but the first part should not match numbers, so probably [a-z][\w]* is the right pattern (must start with a letter).

This looks good! If you test where Unicode is and is not allowed and update the regexps accordingly, I'll merge this. |

As it so happens I was just about to submit a PR for table return and WITH queries. |
