-This class implements autoincrements for Firebird using C<RETURNING>, sets the
-limit dialect to C<FIRST X SKIP X> and provides preliminary
-L<DBIx::Class::InflateColumn::DateTime> support.
+This class implements autoincrements for Firebird using C<RETURNING> as well as
+L<auto_nextval|DBIx::Class::ResultSource/auto_nextval> sets the limit dialect to
+C<FIRST X SKIP X> and provides L<DBIx::Class::InflateColumn::DateTime> support.
You need to use either the
L<disable_sth_caching|DBIx::Class::Storage::DBI/disable_sth_caching> option or
L</connect_call_use_softcommit> (see L</CAVEATS>) for your code to function
-correctly with this driver.
+correctly with this driver. Otherwise you will likely get bizarre error messages
+such as C<no statement executing>.
