Included are patches intended for allowing PostgreSQL to handle multi-byte charachter sets such as EUC(Extende Unix Code), Unicode and Mule internal code. With the MB patch you can use multi-byte character sets in regexp and LIKE. The encoding system chosen is determined at the compile time. To enable the MB extension, you need to define a variable "MB" in Makefile.global or in Makefile.custom. For further information please take a look at README.mb under doc directory. (Note that unlike "jp patch" I do not use modified GNU regexp any more. I changed Henry Spencer's regexp coming with PostgreSQL.)
