=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.
=item disable_sth_caching
specify the charecter that seperates elements (schemas, tables, columns) from
each other. In most cases this is simply a C<.>.
+=item unsafe
+
+This Storage driver normally installs its own C<HandleError>, sets
+C<RaiseError> and C<ShowErrorStatement> on, and sets C<PrintError> off on
+all database handles, including those supplied by a coderef. It does this
+so that it can have consistent and useful error behavior.
+
+If you set this option to a true value, Storage will not do its usual
+modifications to the database handle's attributes, and instead relies on
+the settings in your connect_info DBI options (or the values you set in
+your connection coderef, in the case that you are connecting via coderef).
+
+Note that your custom settings can cause Storage to malfunction,
+especially if you set a C<HandleError> handler that suppresses exceptions
+and/or disable C<RaiseError>.
+
=back
These options can be mixed in with your other L<DBI> connection attributes,
these options will be cleared before setting the new ones, regardless of
whether any options are specified in the new C<connect_info>.
-Important note: DBIC expects the returned database handle provided by
-a subref argument to have RaiseError set on it. If it doesn't, things
-might not work very well, YMMV. If you don't use a subref, DBIC will
-force this setting for you anyways. Setting HandleError to anything
-other than simple exception object wrapper might cause problems too.
-
Another Important Note:
DBIC can do some wonderful magic with handling exceptions,
