Getting fresh 9.1devel I found that jdbc driver failed to obtain tables form the metadata call.
> ResultSet rs = dbMetaData.getTables(null, "%", tableNamePattern == null ? "%"
> : tableNamePattern, new String[]{"TABLE"});
ERROR: no collation was derived for the sort expression at character
1353
HINT: Use the COLLATE clause to set the collation explicitly.

Hacking JDBC driver with adding collate "default" doesn't help:
SELECT NULL AS TABLE_CAT, n.nspname AS TABLE_SCHEM, c.relname AS
TABLE_NAME, CASE n.nspname ~ '^pg_' OR n.nspname = 'information_schema'

Changing encoding/locale from UTF8 to WIN1252 also doesn't help with the
same result
