-----------------------------------------------------------------

Updated the informix translator to support cast using their relevant type names and standard cast syntax - more than like this is valid for only informix 9 or later.  Version 8 may need to use the older pg :: style cast - and version 7 does not appear to support casting.

> I defined a view (see definition below). When I try to select all rows from the view, teiid/informix jdbc driver throws an exception.
> Teiid DDL:
> {code:sql}
> CREATE VIEW U6 (StringCol string,
>     IntCol integer)
>   AS
>     SELECT CONVERT(BQT1.SmallA.IntNum, string) AS StringCol, BQT1.SmallA.IntNum AS IntCol
>     FROM BQT1.SmallA
>     UNION ALL
>     SELECT BQT1.SmallB.StringNum, CONVERT(BQT1.SmallB.StringNum, integer)
>     FROM BQT1.SmallB;
> }
> {code}
> Query:
> {code:sql}
> SELECT * FROM VQT.U6
> {code}
> Source-specific query
> {code:sql}
> SELECT g_1.intnum AS c_0, g_1.intnum AS c_1 FROM smalla AS g_1 UNION ALL SELECT g_0.stringnum AS c_0, g_0.stringnum AS c_1 FROM smallb AS g_0
> {code}
> Actual exception:
> {code:text}
> Caused by: java.sql.SQLException: The statement failed because corresponding column data types must be compatible for each UNION, INTERSECT, or MINUS query.
