The default text search configuration will be set to "simple" ?

Hi there,

what does this message mean? I didn't find any information on the web,
beside of others having similar messages...

------------------------------
The database cluster will be initialized with locales
COLLATE: en_US.UTF-8
CTYPE: UTF-8
MESSAGES: en_US.UTF-8
MONETARY: en_US.UTF-8
NUMERIC: en_US.UTF-8
TIME: en_US.UTF-8
The default database encoding has accordingly been set to UTF8.
initdb: could not find suitable text search configuration for locale
UTF-8
The default text search configuration will be set to "simple".
------------------------------

Thanks for any advice,

Stef
