Message-ID: <E1ros8D-005dr2-D4@gemulon.postgresql.org> (raw)
Refactor predicate_{implied,refuted}_by_simple_clause.
Put the node-type-dependent operations into switches on nodeTag.
This should ease addition of new proof rules for other expression
node types. There is no functional change, although some tests
are made in a different order than before.
Also, add a couple of new cross-checks in test_predtest.c.
