Reject MERGE in CTEs and COPY
The grammar added for MERGE inadvertently made it accepted syntax in
places that were not prepared to deal with it -- namely COPY and inside
CTEs, but invoking these things with MERGE currently causes assertion
failures or weird misbehavior in non-assertion builds. Protect those
places by checking for it explicitly until somebody decides to implement
it.
