Convert v7.0.2-2c1 DB

От

I have a client with a v7.0.2-2c1 database stored on media.  The
database files were stored raw, not dumped.  Their current pgsql version
is 7.1; they do not have v7.0.2-2c1 installed anywhere.

Can I update/add their old db into their new system without installing
v7.0.2-2c1 onto another system to do a dump?

If I have to install v7.0.2-2c1, where is it?  I haven't been able to
find it on the mirrors.  I assume "c1" means it was a release candidate.


TIA!

Lordy, that's a fine mess you've got there. I'm fairly certain that it
wont work if you try to run 7.1.x on top of it. You best bet is to
install a 7.0.x somewhere and then try to copy the data files to that
installation. If you can get that working, install a newer version
(7.3.2?) and do a dump out of the 7.0.x database and see what happens.

As far as what version of 7.0.x to use, I don't recognize that release
so it could very well be a release candidate version, but might also be
a vendor/rpm/debian style version tag. Unless one of the developers
comes forward and happens to have a copy of it, I would grab the 7.0.2
release from the ftp server and try that first. If it doesn't work, try
7.0.1, then 7.0.3.  (Note there is a 7_0_patches tag in cvs, you could
try to use that though i suspect thats closer to 7.0.3 than 7.0.2, and I
don't know how much faith I have in the CVS tags from 2 years ago.) In
any/all cases, always copy the data over, never do anything on the
original files.

Yup...

Any released 7.0.* version should be disk-level-compatible.  Given that
this is a 7.0.2-something and not a 7.0-something I don't think you need
to worry that it might be a 7.0 prerelease.  So as long as you have the
complete $PGDATA directory tree (not a subset that omits pg_log, for
example) I think you should be able to compile any 7.0.* release and
fire it up against that directory tree.  Then pg_dump and away you go.

Check, always keep a pristine copy until you *know* you have a working,
cross-checked, backed-up database in a later version...

Thanks for the replies!

I was able to find ye ol' v7.0.2-2c1 and installed on a test machine.
Dumped db, all is well.
