Обсуждение: Recovering from numbered directories

Has anyone done this? In a fatal crash where the backup only recovered
the numbered directories (data dirs) of a PG installation (i.e. nothing
above the numbered directories), is it possible to reinstall the exact
same version of PG and recover the databases from just those numbered
directories?

Thanks,

Brad

If you haven't got pg_clog you're pretty much screwed :-(
