Tried this. The assertion is hit:

#3  0x0000000000bb9144 in ExceptionalCondition (conditionName=0xd3c7a9 "query->utilityStmt == NULL", 
    errorType=0xc3da24 "FailedAssertion", fileName=0xd641f8 "nodeFuncs.c", lineNumber=2280) at assert.c:54

Any suggestions where best to fix this? transformRuleStmt could be
taught to skip a lot of the per-Query stuff it does in the event that
the Query is actually a NOTIFY, or a check for NOTIFY could be added
further down the stack, e.g. in rangeTableEntry_used. Any preferences?
