Обсуждение: pg_dump
Hi I am having a little more success with the pg_dump command. However, I still seem to have something wrong. I use the following command after navigating to the bin file - pg_dump -h localhost -d Aurel -U postgres After six attempts - Each attempt processed the database and the command prompt announced a successful completion. after 3 attempts - no dump file was found after 2 attempts - a dump file of 0kb was found. after the sixth attempt a good dump file of 4 meg made it to the bin folder. I was able to install this file successfully. Is it usual to require multiple attempts for each successful dump??? If not, does anyone have thoughts on where the problem could be?? Bob Pawley

If that's all you're doing then I'm surprised you ever saw a file at all. pg_dump writes to standard output unless you give it a file name to write to with the -f flag. So, from your bin directory (I normally just put it in my environment PATH variable). ./pg_dump -h localhost -d Aurel -U postgres -f dumpfile.sql or .pg_dump -h localhost -d Aurel -U postgres > dumpfile.sql Erik Jones Software Developer | Emma® erik@myemma.com 800.595.4401 or 615.292.5888 615.292.0777 (fax) Emma helps organizations everywhere communicate & market in style.

Thanks Erik. In between those attempts I did try what you suggest. It failed, apparently due to not making a connection with the server.
