 The MB support is intended for allowing PostgreSQL to handle
 multi-byte character sets such as EUC(Extended Unix Code), Unicode and
 Mule internal code. With the MB enabled you can use multi-byte
-character sets in regexp ,LIKE and some functions. The encoding system
-chosen is determined when initializing your PostgreSQL installation
-using initdb(1). Note that this can be overridden when creating a
-database using createdb(1) or create database SQL command. So you
-could have multiple databases with different encoding system.
