As mentioned in other replies you can use the lower or upper functions
to get consistant case.

If you want case preerved in the table, you can make the searches faster
(at the expense of slowing down updates) by creating an index using a function.

Something like:
create index on table mytable(lower(Name));

Will speed up searches like:
select Name from mytable where lower(Name) = lower('$Name');
