CSV file uses wrong file format (uses JSON instead of CSV)

[cwegener]

This is a most obvious bug, but somehow I'm the first person to report this?

pipelinewise-target-postgres/target_postgres/db_sync.py

Line 351 in bef5a27

json.dumps(flatten[name], ensure_ascii=False)

The Postgresql COPY command does NOT support reading JSON formatted files. It only supports CSV formatted files (and Binary and Text formats)
