Tom Lane 77e760d5cc Avoid crash when rolling back within a prepared statement. ... If a portal is used to run a prepared CALL or DO statement that contains a ROLLBACK, PortalRunMulti fails because the portal's statement list gets cleared by the rollback. (Since the grammar doesn't allow CALL/DO in PREPARE, the only easy way to get to this is via extended query protocol, which treats all inputs as prepared statements.) It's difficult to avoid resetting the portal early because of resource-management issues, so work around this by teaching PortalRunMulti to be wary of portal->stmts having suddenly become NIL. The crash has only been seen to occur in v13 and HEAD (as a consequence of commit 1cff1b95a having added an extra touch of portal->stmts). But even before that, the code involved touching a List that the portal no longer has any claim on. In the test case at hand, the List will still exist because of another refcount on the cached plan; but I'm far from convinced that it's impossible for the cached plan to have been dropped by the time control gets back to PortalRunMulti. Hence, backpatch to v11 where nested transactions were added.
