=item --[no]delete-ignore
default: yes
Do not use C<IGNORE> on C<DELETE> triggers.
This is an special case that affects forign keys handling. Since C<DELETE> only return errors when
there is a problem deleting rows affected by foreign keys, it might be cases when we want to
receive such errors during the program execution to ensure FKs handling is correct.
=item --disable-fk-checks
Disable foreign keys check during rebuild constraints. This option improves the process speed
