 * Motivation
 
-  When you need to execute several queries it involves several network
-  round-trips between your application and database.
-  PostgreSQL frontend/backend protocol supports request pipelining.
-  It means that you don't need to wait for previous command to finish
-  before sending next command. This version of driver makes full use
-  of the protocol feature allowing faster execution.

 * Difference highlights
 
   + 3 API sets: pgsql, apgsql and ipgsql:
-    pgsql maintains backwards compatibility with original driver API,

     apgsql delivers complete results as regular erlang messages,
     ipgsql delivers results as messages incrementally (row by row)

 * Known problems
 
-  Timeout supplied at connect time works as socket connect timeout not query timeout. It passes all tests from original driver except 3 timeout tests.
-  SSL performance can degrade if driver process has large inbox (thousands of messages).
