That's pretty much what pgloader already does for you: if COPY errors out, pgloader split the data in two groups and try to COPY again each of them, until the dichotomy isolates the one row causing COPY the error. Then the given row is appended to the configured reject_data file. See those options for details: http://pgloader.projects.postgresql.org/ copy_every When issuing COPY PostgreSQL commands, pgloader will not make a single big COPY attempt, but copy copy_every lines at a time. This parameter is optionnal and defaults to 10000. reject_log In case of errors processing input data, a human readable log per rejected input data line is produced into the reject_log file. reject_data In case of errors processing input data, the rejected input line is appended to the reject_data file. Maybe this feature should be better highlighted from the DESCRIPTION section of the manpage (which is also the website). Regards, -- dim
