This is documented; it's the very last line of the page you reference in the Github issue:
A transaction cannot be ended inside a block with exception handlers.
Your discussion doesn't answer the specific issue: BEGIN/EXCEPTION/END in pl/pgSQL is implemented by savepoints. What
semanticsshould COMMIT / ROLLBACK have inside of that? Doing a COMMIT / ROLLBACK (at the database level) at that point
wouldlose the savepoints, which would break the BEGIN/EXCEPTION/END semantics.
It's not clear to me what the alternative semantics would be. Can you propose specific database behavior for a COMMIT
orROLLBACK inside a BEGIN/EXCEPTION/END block which retain the savepoint behavior of BEGIN/EXCEPTION/END?
