There isn't really a case-insensitive mode (for various reasons to do with 
locales AFAICT).

There are various case-insensitive comparisons: ILIKE instead of LIKE etc.

A very common approach is to use PG's functional indexes:

SELECT * FROM foo WHERE lower(foo_col) LIKE 'blah%';

along with

CREATE INDEX foo_lwr_col ON foo (lower(foo_col));
