hannu=> create table "bõv"("gbzöh" int);
CREATE

select * from books where title ~* '.*Tom.*');
case insensitive LIKE is not directly supported , but you can do

I understood that you wanted field _names_ to be case-insensitive, not
field values.
Field names are delimited by "", values of type string by ''
