+  also optimizing the pool implementation aggressively.
+  With added support for encoding parametrized lists. E.g.
+  List<int> ids = [ ... ]; // init list with values or get it from parameters
+  result1 = db.query("select * from table where id in (@ids)", { "ids": ids });
+  result2 = db.query("select * from table where id = any (array[@ids]::int[])", { "ids": ids });
+  When using array[@x] syntax in query it's wise to use array type cast (::int[], ::date[], ...)
+  to avoid problems with null list.
