> SAP HANA doesn't support MIN and MAX functions for BOOLEAN type.
> Compared to postgresql, which also has BOOLEAN data type, it seems inconsistent, as postgresql translator mimics MIN and MAX functions by translating them using PostgreSQL specific constructs:
> min(BooleanValue) as bool_and(BooleanValue)
> max(BooleanValue) as bool_or(BooleanValue)
> Similar issue is with CEILING and FLOOR functions.
