Description:
I can only use variants of INT (tinyint, smallint, int, mediumint, bigint)
in partition clauses. Other data types don't work.

How to repeat:
mysql> CREATE TABLE T3 (s1 DECIMAL(1)) PARTITION BY HASH(s1);
ERROR 1461 (HY000): The PARTITION function returns the wrong type

All datatypes should work with KEY partitioning, but currently (5.1/6.0), only integers work with HASH/RANGE and LIST.

also see WL#3481

Most data types works with KEY() partitioning, or the new feature from WL#3352.
