How to use PostgreSQL's "COPY FROM STDIN"

This is an example of how to use PostgreSQL's "COPY FROM STDIN": ```bash psql xxx_development -c "COPY table1(column1, column2) FROM STDIN DELIMITER E'\t' QUOTE E'\x01' ENCODING 'ISO-8859-1' CSV HEADER;" < sub.txt ``` NOTE: The following example where I put the "COPY FROM STDIN" in a file does not work: ```bash # The COPY FROM STDIN SQL statement is in a file named copy.sql. This does not work: psql xxx_development | cat copy.sql ```bash
