When parsing table names in the target URI, we are careful of splitting
the table and schema name and store them into a cons in that case. Not
all sources methods got the memo, clean that up.
See #182 and #186, a pull request I am now going to be able to accept.
Also see #287 that should be helped by being able to apply #186.
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.
