    Replace rewriter's checkQueryHasAggs and checkQueryHasSubLink · 1f2c6f4f
    Tom Lane authored 
    with expression_tree_walker-based code.  The former failed to cope with
expressions containing SubLinks, and the latter returned TRUE for both
SubLinks and Aggrefs (cut-and-paste bug?).  There is a lot more scope for
using expression_tree_walker in this module, but I'll restrain myself
until the 6.6 split occurs from touching not-demonstrably-broken code.
