+The `!psycopg` module
+=====================
+
+Psycopg implements the `Python Database DB API 2.0 specification`__. As such
+it also exposes the `module-level objects`__ required by the specifications.
+
+.. __: https://www.python.org/dev/peps/pep-0249/
+.. __: https://www.python.org/dev/peps/pep-0249/#module-interface
+
+.. module:: psycopg
+
+.. autofunction:: connect
+
+   This is an alias of the class method `Connection.connect`: see its
+   documentation for details.
+
+   If you need an asynchronous connection use `AsyncConnection.connect`
+   instead.
+
+
+.. rubric:: Exceptions
+
+The standard `DBAPI exceptions`__ are exposed both by the `!psycopg` module
+and by the `psycopg.errors` module. The latter also exposes more specific
+exceptions, mapping to the database error states (see
+:ref:`sqlstate-exceptions`).
+
+.. __: https://www.python.org/dev/peps/pep-0249/#exceptions
+
+.. parsed-literal::
+
+    `!Exception`
+    \|__ `Warning`
+    \|__ `Error`
+        \|__ `InterfaceError`
+        \|__ `DatabaseError`
+            \|__ `DataError`
+            \|__ `OperationalError`
+            \|__ `IntegrityError`
+            \|__ `InternalError`
+            \|__ `ProgrammingError`
+            \|__ `NotSupportedError`
+
+
+.. data:: adapters
+
+   The default adapters map establishing how Python and PostgreSQL types are
+   converted into each other.
+
+   This map is used as a template when new connections are created, using
+   `psycopg.connect()`. Its `~psycopg.adapt.AdaptersMap.types` attribute is a
+   `~psycopg.types.TypesRegistry` containing information about every
+   PostgreSQL builtin type, useful for adaptation customisation (see
+   :ref:`adaptation`)::
+
+       >>> psycopg.adapters.types["int4"]
+       <TypeInfo: int4 (oid: 23, array oid: 1007)>
+
+   :type: `~psycopg.adapt.AdaptersMap`
