[SPARK-5753] add JDBCRDD support for postgres types: uuid, hstore and arrays
PostgresQuirks:
* added uuid as StringType
* added hstore as MapType[StringType, StringType]
* added ArrayType
JDBCRDD needed conversion functions (nonspecific to postgres) for ArrayType
and MapType.
* ArrayConversion uses the `ResultSet#getArray(int).getArray()` method, so
it should generally work.
* MapConversion assumes that ResultSet#getObject(int) returns a
`java.util.Map<String,String>`. Maybe this is too strong an assumption?
Not sure how to run/write tests. Would appreciate pointers here.
Thanks!
