By the way, as DECLARE is new as of v14, I think that the interactions
between DECLARE and the past queries qualify as an open item.  I am
adding Michael Meskes in CC.  I got to wonder how much of a
compatibility break it would be for DEALLOCATE and DESCRIBE to handle
EXEC SQL AT in a way more consistent than DECLARE, even if these are
bounded to a result set, and not a connection.
