Short Description
Select from array slices doesn't work

Long Description
When I try to select from array slices it gives strange qrPgSql error. Normal array indexing works, but slices don't.

Sample Code
> create table temp (arr varchar(20)[])
OK
> select arr[1:2] from temp
Error: qrPgSql: Parameter '2' not found
> select arr[1] from temp
OK
