Re: Conflict handling for COPY FROM

Hello,

The attached patch add error handling for
Extra data

missing data

invalid oid

null oid and

row count mismatch

And the record that field on the above case write to the file with appended
error message in it and in case of unique violation or exclusion constraint
violation error the failed record write as it is because the case of the
error can not be identified specifically

The new syntax became :

COPY ... WITH ON CONFLICT LOG maximum_error, LOG FILE NAME '…';
