IndexPredicateAnalyzer decomposes predicates, separating the parts
which can be satisfied by an index from the parts which cannot.
Currently, it only supports pure conjunctions over binary expressions
comparing a column reference with a constant value.  It is assumed
that all column aliases encountered refer to the same table.

@deprecated kept only because some storagehandlers are using it internally
