@ -42,10 +42,15 @@ pg.connect(function(err, client, done) {
var stream = client.query(copyFrom('COPY my_table FROM STDIN')); var stream = client.query(copyFrom('COPY my_table FROM STDIN'));
var fileStream = fs.createReadStream('some_file.tsv') var fileStream = fs.createReadStream('some_file.tsv')
fileStream.on('error', done); fileStream.on('error', done);

*Important*: Even if `pg-copy-streams.from` is used as a Writable (via `pipe`), you should not listen for the 'finish' event and expect that the COPY command has already been correctly acknowledged by the database. Internally, a duplex stream is used to pipe the data into the database connection and the COPY command should be considered complete only when the 'end' event is triggered.
