There is support for plugging into the parser and executor, so that

etc.but I'm still really wish to do this for some very specific needs. I'm not going to completely replace the SQL and

AFAIK HTSQL is very happy producing SQL; why not just let it hand SQL to
Postgres (which it already does...)
Have you by chance talked to Clark or Kirill about this?
