+On every call to L</connection> if the value of this attribute evaluates to
+true, DBIC will invoke
+C<< L<$schema_sanity_checker|/schema_sanity_checker>->L<perform_schema_sanity_checks|DBIx::Class::Schema::SanityChecker/perform_schema_sanity_checks>($schema) >>
+before returning. The return value of this invocation is ignored.
+
+B<YOU ARE STRONGLY URGED> to
+L<learn more about the reason|DBIx::Class::Schema::SanityChecker/WHY> this
+feature was introduced. Blindly disabling the checker on existing projects
+B<may result in data corruption> after upgrade to C<< DBIC >= v0.082900 >>.
+
+Example:
+
+ package My::Schema;
+ use base qw/DBIx::Class::Schema/;
+ __PACKAGE__->schema_sanity_checker('My::Schema::SanityChecker');
+
+ # or to disable all checks:
+ __PACKAGE__->schema_sanity_checker('');
+
+Note: setting the value to C<undef> B<will not> have the desired effect,
+due to an implementation detail of L<Class::Accessor::Grouped> inherited
+accessors. In order to disable any and all checks you must set this
+attribute to an empty string as shown in the second example above.
