Kyoto Tycoon Foreign Data Wrapper for PostgreSQL

Thanks to the Blackhole Foreign Data Wrapper for PostgreSQL for providing a good template of how to build FDWs for PostgreSQL.

##To Build: make (sudo) make install

A note about transactional support: This FDW supports Kyoto Tycoon transactions via LUA scripts. Therefore, KT needs to be compiled with LUA support. To do this, run
./configure --enable-lua
when compiling KT.

Furthermore the ktserver has to be started with tranactions.lua loaded:

./ktserver -scr <fdw directory>/transactions.lua

If you want to disable transactions remove -DUSE_TRANSACTIONS from the Makefile in the FDW.

##To Test: make installcheck

##Usage:

CREATE SERVER <server name> FOREIGN DATA WRAPPER kt_fdw OPTIONS
(host '127.0.0.1', port '1978', timeout '-1');
(the above options are the defaults)

CREATE USER MAPPING FOR PUBLIC SERVER kt_server;

CREATE FOREIGN TABLE <table name> (key TEXT, value TEXT) SERVER <server name>;

Now you can Select, Update, Delete and Insert!
