+{-| This module represents an extension to 'hasql-pool', it allows for a mix of dynamic credentials
+    and static settings for connections in a pool.
+    Due to the fact that the module tries to extend 'hasql-pool' rather than rewrite it, the exposed API relies on
+    combining existing 'hasql' types with new types, whereas a rewrite would just extend the original types.
+    It is done so to simplify maintenance of the extended functionality and make it more compatible with any
+    future development of 'hasql-pool'.
