Обсуждение: [urgent]need help transferring database to another server
our postgres server died yesterday and i need to retrieve the data from that server to another one. the server was running postgres 6.5 and i need to move it to another server also using postgres 6.5. i am unable to do a pg_dumpall for some reason, so i was wondering if i copy the data directory from server to another, will the new server be able to read the data and i can dump the data? any help would be appreciated.

It _should_ work.
Note, however, that pre-WAL versions of PostgreSQL are not really
crash safe. There is a possibility that your data is in an
inconsistent state.
Are you _really_ stuck with 6.5? I'd strongly suggest you
investigate upgrading after you recover your data, if you can.

I should have qualified that: assuming the endian-ness and other such
attributes of the systems are the same. You can't do that from, say,
Linux to Solaris. Your best bet is to go to a system as similar as
possible.
