=item on_connect_do
-This can be set to an arrayref of literal sql statements, which will
-be executed immediately after making the connection to the database
-every time we [re-]connect.
+Specifies things to do immediately after connecting or re-connecting to
+the database. Its value may contain:
+
+=over
+
+=item an array reference
+
+This contains SQL statements to execute in order. Each element contains
+a string or a code reference that returns a string.
+
+=item a code reference
+
+This contains some code to execute. Unlike code references within an
+array reference, its return value is ignored.
+
+=back
+
+=item on_disconnect_do
+
+Takes arguments in the same form as L<on_connect_do> and executes them
+immediately before disconnecting from the database.
+
+Note, this only runs if you explicitly call L<disconnect> on the
+storage object.
