No, you've been used to MySQL case insensitity methinks...

Use ILIKE:

SELECT * FROM table WHERE name ILIKE 'jane smith';

Or LOWER:

SELECT * FROM table WHERE LOWER(name) = LOWER('JANE SMITH');

(it'll help you to make a functional index in this case)

Use LOWER:

SELECT * FROM table WHERE LOWER(name) = LOWER('JANE SMITH') ORDER BY
LOWER(name);
