The COPY command can import data to Postgres if access to text, CSV, or binary format data. For example, the COPY TO command outputs the content of a table to a file. You can also use the COPY FROM command to load the data from a file to the table. The file mentioned in the COPY command must be accessible by the Postgres user and should be specified from the perspective of the Postgres server.

The command can also use a SELECT query to load data to a table. It also allows you to specify a list of columns to insert the data into instead of the whole table. On successful completion, the COPY command outputs result in the format COPY count, denoting the number of rows inserted by the command.īoth the text and the CSV file formats allow you to specify a delimiter.
