<para>

Selects the text search configuration that is used by those variants

of the text search functions that do not have an explicit argument

specifying the configuration.

See <xref linkend="textsearch"> for further information.

The built-in default is <literal>pg_catalog.simple</>, but

<application>initdb</application> will initialize the

configuration file with a setting that corresponds to the

chosen <varname>lc_ctype</varname> locale, if a configuration

matching that locale can be identified.
