I agree that this looks like a bug, since your example shows that the
same function works as-expected in an ordinary expression but not in
a CALL.  The dependency on AUTOCOMMIT (that is, being within an outer
transaction block) seems even odder.  I've not dug into it yet, but
I suppose we're passing the wrong snapshot to the CALL arguments.
A volatile function wouldn't use that snapshot, explaining Pierre's
result.
