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

There is a way to solve "", the quoted null string as null in integer column, use FORCE_NULL option :

\copy table_name FROM 'file.csv' with (FORMAT CSV, FORCE_NULL(column_name));
