This option is dangerous and allows to skip ALL triggers when loading data against PostgreSQL. This includes foreign key constraints definitions and will allow loading data out of order. When using both the options "create no table" and "disable triggers" it will be possible to load data into a schema prepared by your favorite external tool, at the cost of not validating FK constraints. Use with care. Fix #167.
