I seem to have inadvertently upgraded to postgres 8.4 when upgrading to ubuntu karmic. Now it seems I cannot read the 8.3 dumpfile:
pg_restore: [archiver] unsupported version (1.11) in file header
Thats wicked! I’ll try and push everything back to 8.3 again. Any of you postgres experts got an idea about 8.3/8.4 compatibility?

pg_restore --ignore-version will solve your problems in all likelihood.
The command line is you friend. Do not fear it. pg_restore --help
would have saved a few CPU cycles.

That's weird, I recently got a pg backup from Ola which I could not restore
because I was running 8.3 and he 8.4... (I upgraded and it worked).
I have had the same problem as Lars (I dumped on my laptop’s 8.4 and couldn’t restore on the server’s 8.3). But I thought the other way should work - apparently not. You dont in fact need to change the whole server, it is only the pg_restore that needs replacement. I solved my own problem by accessing the server from the PgAdmin on my laptop, thus using the 8.4 restore to restore to add data to the 8.3 database (at least that’s what I think I did, it’s been some time…)

This is really not a good idea. There can be changes between minor
versions, this is why Postgres is picky. Using a different version of
pg_restore with a different Postgres database could be a recipe for
disaster.
Having said this. DHIS utilizes essentially no custom aspects of
postgres, so differences between minor versionf of postgres "should"
present no issues, but there is no guarentee.
As usual, unless there is a reason to upgrade a production database
package, it probably is not a good idea to do so, just because a new
one has been released unless it is thoroughly tested.

Agree that it is not ideal, but it did work fine in this case.

Yeah, but in general people will always install the newest version, just like Bob inadvertently had, and I don’t think it makes sense for us to require everyone to use 8.3, for the reasons you state above (we dont use any specific features, and --ignore-versions seems to work).
Postgres is very picky about versions but generally dumps are
compatible between versions, at least in terms of dhis which utilizes
no custom postgres functionality. Google will tell you how to coerce
postgres into accepting dumps from different versions. Jason
