=head1 NAME
DBIx::Class::Schema::Loader::DBI::Component::QuotedDefault -- Loader::DBI
Component to parse quoted default constants and functions
=head1 DESCRIPTION
If C<COLUMN_DEF> from L<DBI/column_info> returns character constants quoted,
then we need to remove the quotes. This also allows distinguishing between
default functions without information schema introspection.
