I would like to add a note about the SQL standard here.
Some people have been using terminology that a "function" does this and
a "procedure" does something else. Others have also mentioned the use
of a CALL statement to invoke procedures.
Both procedures (as in CREATE PROCEDURE etc.) and the CALL statement are
specified by the SQL standard, and they make no mention of any
supertransactional behavior or autonomous transactions for procedures.
As far as I can tell, it's just a Pascal-like difference that functions
return values and procedures don't.
So procedure-like objects with a special transaction behavior will need
a different syntax or a syntax addition.
