This fixes my problem, thank you.
There are two switch statements in that function, and they have
overlapping purposes. Can't we just always set needlabel in the first
switch statement, and remove the second switch statement?
When I refactored it to do that (attached), I noticed that if showtype
== -1, it returns before appending the collation. I don't see any reason
those should be related, so I removed the early return (I don't think
there's an actual bug there, though).
There are more diffs in the contrib tests, also included in my version.

Fine with me.
