> TEIID-3282 changed the semantics of the WEEK function to use the iso behaviour.
> The Vertica database has WEEK_ISO function that returns the iso week, but the translator does not have that alias set.
> This results in the query (the datevalue in question is 2000-12-31)
> {code:sql}
> select week(datevalue) from source.largea where intkey = 365
> {code} 
> to return 54, when the correct value is 52.
