[Pgpool-hackers] patch "Caching query results in pgpool-II"

[Masanori Yamazaki]

Hello, hackers

I have implemented a function caching query on memcached.
I am sending the patch file and it's so nice to give me some opinions.

Main program which I implemented is as below.
- Search for cache data on memcached by using md5 which converted SELECT
into.
- Set data on memcached. The key is md5 which converted  SELECT into.
The value is RowDescription, DataRow from Backend.
