If you really have single quotes around the name of your text column,
position is looking for your string in that literal text. It should
not have single quotes. If your column name is a reserved word or has
special characters you can double quote it.
I also think you want select * "FROM" not "IN", so
SELECT * FROM customers WHERE position('sub_string' in
customers_text_column) > 0;

It depends on the locale settings when the cluster was created. On US
systems, typically uppercase precedes lowercase. E.g. "Zip" is before
"apple" in an ascending sort.
