At the source end, yes. At the destination one of the tests we perform for a fully and correctly copied file is the file size; a smaller file size we take to mean that the copy is still in progress. We check that before we actually read the file, so it would complicate things considerably to allow for variable file sizes. -- Simon Riggs 2ndQuadrant http://www.2ndQuadrant.com ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
