Rem we will use a canonical representation for base filter conditions
Rem like (T.col < 10). In this case clauseOp will be LT, lhs will be
Rem T.col and rhs will be 10. We will use a post fix notation for
Rem expression operands to make parsing simple. The dependent list
Rem contains the list of higher level entities (like clauses/queries)
Rem that reference the clause. When the dependent_list becomes empty,
Rem the clause is no longer needed and can be deleted.

Rem each dependent may have its own reference count for the clause
Rem indicating how many times the same clause was generated by this
Rem dependent. Optionally, this can be enhanced to include per
Rem dependent stats such as how many times the clause was true but the
Rem dependent was FALSE. In the case of multi-table queries that involve
Rem JOINS, the dependent is set to the queryId. If the clause
Rem evaluates to TRUE, we must further lookup
Rem chnf$_query_table based on the queryId, objn to determine if there
Rem are any dependent objects for which predicates need to be updated.
Rem If a query is being deleted, we must delete all clauses
Rem whose dependent is set to every (queryId, objectId) tuple.
