You do know that under 7.1, the important LC_ values are the ones that
initdb sees, not the ones that the postmaster sees, right? Can't tell
from this snippet whether you initdb'd in Swedish locale or not.

Is this a bug? I'd sort of think that '' is not lower case
(although maybe my mail reader isn't presenting it in the right
font ... it looks like an accented upper case I to me, but what
do you think it is?). Shouldn't you say "where lower(name) like
lower('%%')"? Or perhaps use ILIKE to get a case-insensitive
compare.
