Обсуждение: Import Database

This is a little odd, and I can't quite figure out how to do it.

I have a postgres 7.2.2 database, without the DB_VERSION file, so I'm assuming
this is an "alternate location" - as you can tell, I'm not a DBA.  Anyway,
the machine it was on got hacked, and I backed off the things I thought were
important, reinstalled the OS and put the other things, including this DB,
back into place.  Problem: I don't have the /var/lib/pgsql part of my old
installation, and now I have an apparently-good postgres 7.2.2 installation,
and an apparently-good database, but I cannot get the postgres server to
recognize the old database.

Obviously, without this I cannot dump and re-import, so I'm at a bit of a lss
as to what to do.  Is it possible to tell postgres that a database already
exists, and just to use it?  (I do know the information on the user who
owns the database, and the old passwords and such.)

Thanks

Exactly what did you back up?  What are the contents of the directory
you are trying to "attach" ?

If you didn't backup a pg_clog directory, you are pretty much hosed, I
think.
