Greetings!

PostgreSQL specific DO is not supported and you will need to provide or sponsor an implementation when you are interested in this particular feature.

[zdhuangelephant]

It is working by only passing through the text block. You would at least introduce a DO $$BEGIN ... END$$ statement and certainly you will want to parse this block in order to get the AST of your INSERT ... statement.
