-*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.

 This module __only__ works with the pure JavaScript bindings.  If you're using `require('pg').native` please make sure to use normal `require('pg')` or `require('pg.js')` when you're using copy streams.
 
-Before you set out on this magical piping journey, you _really_ should read this: http://www.postgresql.org/docs/current/static/sql-copy.html, and you might want to take a look at the [tests](https://github.com/brianc/node-pg-copy-streams/tree/master/test) to get an idea of how things work.

-
-Take note of the following warning in the PostgreSQL documentation:
-> COPY stops operation at the first error. This should not lead to problems in the event of a COPY TO, but the target table will already have received earlier rows in a COPY FROM. These rows will not be visible or accessible, but they still occupy disk space. This might amount to a considerable amount of wasted disk space if the failure happened well into a large copy operation. You might wish to invoke VACUUM to recover the wasted space.
