> Partition pruning metadata is not extracted for the following queries:

> CREATE TABLE t (c1 INT, c2 INT, c3 INT, PRIMARY KEY (c1, c2))
> INSERT INTO t SELECT * FROM t WHERE c1=? and c1=?

> .addKeyColumn("C1", NativeTypes.INT32)
> .addKeyColumn("C2", NativeTypes.INT32)
> .addColumn("C3", NativeTypes.INT32, true)
