| Hi All- I'm new to Postgres and have a question about bulk loading from streams. I know that I can bulk load from a file using COPY. Is it possible to use a stream instead of a file? If so, and I limited to stdin? I'm attempting to stream data from a remote database into my Postgres instance. I don't want to insert each tuple individually using jdbc since that would be horribly slow... Thanks, Chris ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match |

That should replicate the remote database to your host over the network. You can also use the "-h hostname" option on psql to exectue a "copy to file" on the remote host. The file ends up on your local system, where you can do a subsequent copy from file. Hope this helps, |
