PostgreSQL extension that can skip faulty lines in COPY

When users load large data sets (from S3 or files), these datasets might have a few bad records. Most data warehousing solutions can be configured to skip over a predefined number of bad lines.

This has also been discussed for PostgreSQL: https://wiki.postgresql.org/wiki/Error_logging_in_COPY

This task proposes to extend COPY to skip over a configurable number of records.
