Description:
# SELECT ROW (1) OVERLAPS ROW (2);
ERROR: XX000: unrecognized node type: 656
LOCATION: transformExprRecurse, parse_expr.c:359
I'm not sure why this even parses, as it's not documented to do so. I do
notice, however, that in makeOverlaps in gram.y creates a recursive list
when largs or args has only one argument, which seems wrong to me.
