7.4 - data recovery

Hi,

I'm not postgresql experienced user, so please forgive me, if I missed
something obvious!

I have the following problem:
1. Partition with postgresql v.7.4 data has been damaged
2. No backups!
3. I've recovered some files and it looks to me they're from
$PGDATA/base/data/xxx (it looks this is the complete folder)
4. No other files! (no pg_clog, pg_xlog etc)

I've tried to deal with the issue in the following way:
1. I created new database (named test) on new 7.4 PG instance (it creates
/var/lib/postgresql/data/base/121339 folder for data)
2. I stopped the postgresql
3. Then I replaced the data in /var/lib/postgresql/data/base/121339 with
my just recovered files
4. Then I started DB

When I connect to "test" database I see no tables in the schema. Something
went wrong! ;-(

I realise this is not a best way (correct one) to recover data from
damaged partition, but I have no idea how to proceed. It was my desperate
try to recover those data - does anyone can advice me how to proceed? Is
it possible to recover it at all?

To clarify the issue, this is what I've got now: (the result of ls -l
command in recovered directory)

Thanks in advice for any help!

best regards,
Bartek
