JSON Data Loading example does not work out of the box

[adnan-alhomssi]

I tried following the JSON: German Commercial Register example from our website and encountered the following exception:

postgres=# copy register_json from '/home/adnan/data/de_companies_ocdata.jsonl';
ERROR:  invalid csv in line 1, column 1: invalid number format for integer: no digits found in "{"all_attributes":{"_registerArt":"HRB","_register". Could not detect a valid CSV dialect.

Our examples/tutorials should just work when pasted (until we have a better CSV dialect detection xD)
