My apologies -- my mail filters were overeager, and I didn't see it.

Well, dblink is simply calling SRF_RETURN_DONE() when the current
context is the multi-call memory context. We could outlaw that
practice, but that risks breaking out-of-tree SRFs that do something
similar. I think better would be to figure out a more appropriate
memory context to switch into before deleting the multi-call context.
