Tom Lane 5db2e83852 Rethink the order of expression preprocessing: eval_const_expressions ... really ought to run before canonicalize_qual, because it can now produce forms that canonicalize_qual knows how to improve (eg, NOT clauses). Also, because eval_const_expressions already knows about flattening nested ANDs and ORs into N-argument form, the initial flatten_andors pass in canonicalize_qual is now completely redundant and can be removed. This doesn't save a whole lot of code, but the time and palloc traffic eliminated is a useful gain on large expression trees.		2005-03-28 00:58:26 +00:00
