-Introduction	
-============	
-
-ProxySQL is a high performance, high availability, protocol aware proxy for MySQL and forks (like Percona Server and MariaDB).	
-It now also supports PostgreSQL (protocol-aware proxying for PostgreSQL), providing the same high-performance, HA and manageability features for Postgres workloads.
-All the while getting the unlimited freedom that comes with a GPL license.	
-
-Its development is driven by the lack of open source proxies that provide high performance.
