However, I've upgraded 7.1.3 to 7.4 and I had lots of problems until I used the pg_dumpall from 7.4. In my case, it had two boxes so I ran the pg_dump from the 7.4 box to the 7.1.3. Basically, you are dumping over the network. Its very straight forward. All you have to do is set up the appropriate parameters in the pg_hba.conf file of your 7.1 box and follow the directions in the man page of pg_dumpall (see the "-h" parameter). If you are not on a network, you could install 7.4 version in a different directory and configure to run on a different port. You still dump via IP this way. You can run both systems head to head that way and see how things went. Good luck- -- Keith C. Perry, MS E.E.

You need to do a dump and reload to go between major releases (e.g. from 7.1.x to 7.2.x). If you overlaid your 7.1 binaries you are going to have to uninstall 7.4 and reinstall 7.1 and dump the database. If you have the 7.1 binaries and the 7.4 binaries available, you should use the 7.4 pg_dump(all) to do the dump as it is better about handling dependencies and some other things.

Yes, you need to reinstall 7.1, then use the pg_dump/pg_dumpall from 7.4.2 to dump the data out of the running 7.1 database. If you setup the two databases on seperate machines this is easier to do, and how I usually upgrade Postgresql at work.

Bruno, a ton of work went into making the pg_dump in 7.4 capable of dumping the older versions back through, I believe 7.0 or 6.5 or so. Basically, the recommended method now is to just use 7.4's dump of a running 7.1 database to get the dump.
