[GENERAL] Disaster recovery (server died)

[Miguel Miranda]

Hi, the worst have ocurred, my server died (cpu), so i reinstalled another
server with the same postgres version.
I have the old data directory from the old server, how can i restore my
databases from this directory to the new one?
I dont have a backup (pg_dump,etc), just the main previus live data
directory from the old server.
