Question about PG_CONTROL_VERSION 1

[Condor <condor@xxxxxxxxxx>]

Hello,

I try restore from old hard drive an database. The system is not 
working, so I install new server, install postgres 9.0.3 and try to copy 
postgresql dir to new location but I receive error:

2021-04-14 11:47:04.205 UTC [10285] FATAL:  database files are 
incompatible with server
2021-04-14 11:47:04.205 UTC [10285] DETAIL:  The database cluster was 
initialized with PG_CONTROL_VERSION 1, but the server was compiled with 
PG_CONTROL_VERSION 903.
2021-04-14 11:47:04.205 UTC [10285] HINT:  It looks like you need to 
initdb.

How I can start the database or a way to check which files are used for 
database that I need it and copy only them ? Did I have a broken files 
(probably) ? Is there a way to copy only needed files or some way to 
export the data ?

Thanks,
HS
