Been there, done that...
We had this same issue. You need to initially build your databases with
the correct locale. See the following:
http://www.ca.postgresql.org/users-lounge/docs/7.2/postgres/charset.html#AE
N16601
Response is the requirement to re-initdb with the correct value set for
env_var "LC_COLLATE". In fact, I suggest to do an initdb without setting
it and you should observe a message during processing stating the LIKE
queries will not support indexing. Then set the variable and do it again
and observe that you don't receive this message.
As far as we know, you'll have to dump out and then restore your data.
If you are looking for more info, suggest you search Google groups for
"Postgres Like Seq Scan" and you'll see you are in good company.
