Turkish? Are you using a Turkish locale? If so this is probably the
infamous I/i problem. I believe we've got that fixed for 8.0, but there
isn't any simple solution in older versions ... other than not using
Turkish LC_CTYPE which you probably won't be happy with either. Search
the PG archives to see the workarounds people have used ("turkish"
should be a good search keyword).
