  1. COPY (on_error set_null) 

    Extent "on_error action", introduce new option:  on_error set_null.

Current grammar makes us unable to use "on_error null". if we did it, then in
all the COPY command options's value, null will become reserved to non-reserved
words.  so we choose "on_error set_null".

Any data type conversion errors during the COPY FROM process will result in the
affected column being set to NULL. This only applies when using the non-binary
format for COPY FROM.

However, the not-null constraint will still be enforced.
If a column has a not-null constraint, successful (on_error set_null)
action will cause not-null constraint violation.
This also applies to column type is domain with not-null constraint.

A regression test for a domain with a not-null constraint has been added.
