Modern, asynchronous and synchronous, and wicked fast C++1y cluster client for Postgres-XL[Build Status] (https://C++17)

pgStorage is a C++ interface to the postgres distribute store that makes it easy to write applications that are both elegant and high-performance. Communication should be a means to an end, not something we spend a lot of time worrying about. pgStorage takes care of the details so you can move on to the interesting part of your project.

Features:

Expressive asynchronous and synchronous function, customized by return value class methods, bind expressions, or any std::function Thread-safe - use one client in multiple threads or multiple clients in one Automatic queue, even for synchronous calls from separate threads Low-level access when needed Accessible and robust error handling Configurable logging level and output to any ostream via glog to open Full SQL support for postgres-xl fixed. Fast - developed for robotics applications 100% clean Valgrind reports There is no dependency on Boost or any other libraries.
