isCopyUpsert()
public boolean isCopyUpsert()Returns whether COPY operations should use upsert instead of insert.
COPY will INSERT records by default. This is consistent with how COPY on PostgreSQL works. This option allows PGAdapter to use InsertOrUpdate instead. This can be slightly more efficient for bulk uploading, and it makes it easier to retry a failed non-atomic batch that might have already uploaded some but not all data.
