Subject: parser that could handle "FROM... SELECT..." as well as "SELECT... FROM..."

Hello Postgres folks,

After reading
https://jvns.ca/blog/2019/10/03/sql-queries-don-t-start-with-select/
and the discussions at https://news.ycombinator.com/item?id=21150606
I'd also like to write "FROM... SELECT..." instead of "SELECT... FROM...".

Postgres doesn't support this though. Would it be possible to please add
parsing support for this syntax as well?

Somebody mentioned:
Engines don’t run sql directly. They make an AST, make an intermediate
representation of instructions and then execute.
So if it results in same AST, the parser should be flexible.

Thanks!
Marius
