I hadn't thought about using rsync; that's a great idea!

Is there somewhere this could be documented? In an FAQ maybe?

[DOCS] question about markup

[Robert Treat]

someone suggested that the insert command at the end of 
http://wwwmaster.postgresql.org/docs/8.0/interactive/dml.html  would be 
better if it were a link like the copy command is.  Is there some reason not 
to make it a link? I notice most commands are not done this way.
