Thanks to all who responded. Tom also wrote this, earlier: > In any case, Bryn's right, the combination of a SET clause and a PARALLEL > clause is implemented incorrectly in AlterFunction. I'm taking what I've read in the responses to mean that the testcase I showed is considered to be evidence of a bug (i.e. there are no semantic restrictions) and that fix(es) are under consideration. I agree that, as long as you know about the bug, it's trivial to achieve your intended effect using two successive "alter function" statements (underlining the fact that there are indeed no semantic restrictions). I hardly have to say that the point is the risk that you silently don't get what you ask for—and might then need a lot of effort (like I had to spend) to work out why.
