The following bug has been logged online:

Bug reference:      2540
Logged by:          radoslaw wisniewski

PostgreSQL version: 8.1.4-2
Operating system:   Linux
Description:        function upper(..) and operator 'like' problem
Details:

function upper combined with like opertaor and german umlauts (db encoding
UTF8) fails.

Working example in some query:

select * from test where upper( name ) like upper('%Störk%')

Not working example:

select * from test where upper( name ) like '%STÖRK%'

function lower seems to have the same problem.

You have probably configured the wrong locale, but you have not given
nearly enough information to reproduce your problem.
