I've been working on Lime https://codeberg.org/gregburd/lime and a replacement of flex and bison in Postgres using Lime https://github.com/gburd/postgres/tree/lime which isn't yet stable or ready but the intention is/was to use a new parser that has the ability to be extended (changed) at runtime so that our extension authors can do some more interesting tricks.

Not a finished branch, but something to talk about for sure.
