Dear List, As many of you know every time one wants to upgrade to a major server version, as I want to do now, there is a need for pg_dumpall and restore. This is a huge undertaking and requires lots of testing and planning. I do hope that in the future this requirement will be dropped.
There is currently some discussion about an upgrade tool, but there has been discussion before. It's not a simple problem, and it won't reduce the need for testing, just the dump/restore.
I am now upgrading from 8.1.9 to 8.2.4 and pg_dumpall gives a dump file which has a command "\connect template0"
OK. If you're not in a hurry, and can wait a few months 8.3 will be out.
Normally template0 does not accept connection but I found a way to make that happen in the documentation on postgresql website. But is it generally safe to accept the connection for template0 all the time? Why won't pg_dump include a line to accept connection for template0 just before it writes "\connect template0" and then remove the permission after it is done with template0?
Might be a bug, but first; did you dump using 8.2's pg_dumpall? -- Richard Huxton Archonet Ltd
