Re: [GENERAL] Tape backup, 2 versions, same database name, which is pg_dump
It needed /bin in the path. Works fine this way. /usr/local/pgsql/bin/pg_dump -p 55432 -U postgres -C -D -f /tmp/$(date+%F)owl.sql owl Thank you again for your help. *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** Margaret Gillon, IS Dept., Chromalloy Los Angeles, ext. 297 This e-mail message and any attachment(s) are for the sole use of the intended recipient(s) and may contain proprietary and/or confidential information which may be privileged or otherwise protected from disclosure.

How do I call the pg_dump from the 8.1.4 version?You'll probably need to specify an absolute path. Are both the client and server applications running on the same server? If so, you might need to get your consultant to tell you where the client applications for the 8.1.4 installation were actually installed. By default, postgres installs both client and server applications into /usr/local/pgsql, but at least one of your installations must be in a different location; otherwise, you probably couldn't have two versions of the postmaster running concurrently.--Thomas F.

Re: [GENERAL] Tape backup, 2 versions, same database name, which is pg_dump backing up
Your confirmation is correct with one slight technical exception: specifying the port doesn't technically cause the system to know which version of postgres to use.In my previous post, I forgot to mention a related note: the version of pg_dump that you're using matters slightly. pg_dump can typically be used with older postgres installations, but not newer ones. So you should prefer using the 8.1.4 version of pg_dump to dump at least your 8.1.4 postmaster, but probably also your 7.3.4 postmaster.A 7.3.4 pg_dump client will probably not be able to run against an 8.1.4 postmaster.Otherwise, pg_dump doesn't really care about the version as much as it cares about being able to connect to a postmaster. That's what specifying the port helps it do. When you don't specify the port, it just tries port 5432. If it finds a postmaster listening there, great, it will try to dump it; otherwise, it will fail with a complaint that it couldn't connect to anything on 5432. --Thomas F.

Re: [GENERAL] Tape backup, 2 versions, same database name, which is pg_dump backing up
You'll need to specify the non-default port explicitly in your pg_dump command in order to back up the postmaster running on 55432.E.g., pg_dump -p 55432 -U postgres -C -D -f /tmp/$(date+%F)owl.sql owlBy default, the postgres command-line utilities attempt to connect to 5432 (or $PGPORT or whatever is configured as the default port).In the meantime, you're still backing up the 7.3.4 postmaster with that script. --Thomas F.

To make sure everything was okay we left the server so that both versions of Postgresql load. 7.3.4 loads on the default port of 5432 and 8.1.4 loads on port 55432 . My database was moved into the new version so both the old and new databases have the same name. I have a little .sh file that runs a tape backup using pg_dump and I am wondering if both versions are running how do I know which version of the pg_dump is running and which version of the database is being backed up? The backup command I use is pg_dump -U postgres -C -D -f /tmp/$(date+%F)owl.sql owl then I use tar to copy the file to tape. Please answer to me as well as the list, I am on digest.
