IMHO, it wouldn't look logical to support LATERAL for "table_proc" but
disallow it for "joined table".
But LATERAL **is** a table_primary, it doesn't **use** table_primary (at
least not until you dive down into the select_expr), the rule would become
I understood that you suggested to allow "LATERAL table_proc" (for
procedures). "LATERAL derived_table" is by standard, no questions here.
But you suggested to disallow "LATERAL ( joined_table )". This is what I
see as inconsistent. I'd rather disallow LATERAL for both non-standard
rules, or allow it for both.

: table_proc

This is how I see it too.
Note that this may be an indication that I need to revise my opinion on
point 3 though.
It seems so ;-)
