Use "your_field_name" for case-sensitive fields name.

In what way, in how you refer to them or in how you compare them?
PostgreSQL has no built in case-insensitive types, but there is an
addon for citext or something like it that makes a case insensitive
type. Or you can make a case insensitive index and use that.

create table mytable (id int, field x int, fieldy int, field1 text);
create index mytable_field1 on mytable ((lower(field)));
select * from mytable where lower(field)='abc';
