 =head1 DESCRIPTION
 
 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.
+L<auto_nextval|DBIx::Class::ResultSource/auto_nextval> 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. Otherwise you will likely get bizarre error messages
-such as C<no statement executing>.
-
-For ODBC support, see L<DBIx::Class::Storage::DBI::ODBC::Firebird>.
+such as C<no statement executing>. The alternative is to use the
+L<ODBC|DBIx::Class::Storage::DBI::ODBC::Firebird> driver, which is more suitable
+for long running processes such as under L<Catalyst>.
 
 To turn on L<DBIx::Class::InflateColumn::DateTime> support, see
 L</connect_call_datetime_setup>.
