When I worked on parametrised DO statement, I had to solve following issue:
DO currently is a utility command, not a query. Do you mean to change
that?
Also, did you think about a lambda construct, which is basically
allowing functions to be defined

I like this idea. This gets rid of both the how to pass parameters
and the how to return results issues that exist with DO, as

I'm not sure I can understand the difference between that and the use

this is similar to temporary functions - you need some

What's to solve? Presumably the WITH function name would take
precedence over anything in the catalogs, the same as WITH query names
take precedence over actual tables.

When I worked on parametrised DO statement, I had to solve following issue:
Syntax is:
DO (param list) $$ ... $$ LANGUAGE ... USING expr_list
What is correct way for evaluation of expr_list with specified target types?
I used two techniques:
