You could preface all your queries with something like:

select * from foo where lower(bar) = lower('qualifer');

But that seems a bit silly.


And also it would prevent the optimizer from using any indexes on "bar". Not a good idea.

You could use a functional index to solve that.

CREATE INDEX lower_bar_idx on foo(lower(bar));
