we have a PostgreSQL 8.2 database on an xfs filesystem. By mistake the first blocks of this filesystem were overwritten. An xfs_repair reconstructed the superblock and also found many orphaned files and directories. Actually, all we have on the filesystem now is in "lost+found". ;-) When I look in "lost+found" I have many files that *could* be database files, but since the original name of the files is unknown I cannot tell for sure. I have found a directory that looks like the original "data" directory, with stuff like "postmaster.log", "pg_hba.conf" and even subdirectories "base", "global" etc. in it. I have been able to start postgresql from this directory, but when I tried to access the most important database I got a message that the database directory could not be found. Indeed, this directory is missing in "base", but there is a chance that some of the other files might be the original content of this directory. Is there any way to find out which of the files is really a postgres data file? Or even for which database? Although the database file and page layout are described in the manual, I could not find an exact description of the file format, e.g. any magic numbers at the beginning of the file.
