+flask version of xinetd for pgsqlcheck. 
+The idea is we run query to postgres `select pg_is_in_recovery()`. This query will return true or false.
+So, if it is true, then our instance is standby node, otherwise it is primary node. If the node is unreachable, then it will marked as DOWN. 
+This script is suitable for creating high-availability postgresql behind haproxy.
