we had a server crash today - had to fsck and postgres is corrupted now

if i try a pg_dump i get:

inetmain:/tmp/tests$ pg_dump -c -v -d factline1 > /tmp/factline1_20011025_144800.sql
--  saving database definition
getDatabase(): SELECT failed.  Explanation from backend: 'ERROR:  pg_atoi:
error in "t": can't parse "t"

i get the same error if i try to dump a table.

i deleted all indexes as there were lot's of problems with them but this
didn't help ether.

i changed src/backend/access/transam/xlog.c

if (XLByteLT(LogwrtResult.Flush, record))
  elog(STOP, "XLogFlush: request is not satisfied");


if (XLByteLT(LogwrtResult.Flush, record))
  elog(DEBUG, "XLogFlush: request (%u, %u) is not satisfied --- flushed to (%u, %u)",
  record.xlogid, record.xrecoff,
  LogwrtResult.Flush.xlogid, LogwrtResult.Flush.xrecoff);

because otherwise postgres wouldn't even start.

my question: how can i either get a dump of my data or a running database
back. i did a backup of /var/lib/postgresql/data before removing indexes so
i still have the version after the crash.
