Is the copy protocol (aka PQputCopyData and PQputCopyEnd) designed to send gigabytes of data with just one "copy ... from stdio" query, and is there a way to be notified of a potential error before calling PQputCopyEnd? Or do I have to send my data in small chunks (for example batch of 10000 rows), issue a PQputCopyEnd, check for errors, and continue with the next chunk?
I would batch the data, maybe 1000 lines or even 100 lines at a time if these errors are at all frequent. put the errored batches in an exception list or something so you can sort them out later.
