PG COPY error: invalid input syntax for integer

Question

Running COPY results in ERROR: invalid input syntax for integer: \"\" error message for me. What am I missing?

My /tmp/people.cs

Answer 1

I got this error when loading '|' separated CSV file although there were no '"' characters in my input file. It turned out that I forgot to specify FORMAT:

COPY ... FROM ... WITH (FORMAT CSV, DELIMITER '|').
