How to restore pg from /var/lib/pgsql?

Question

linux

The operating system died, but with the help of a boot disk, I copied the database.
However, it turned out to be more difficult to restore them than I thought.
What I already did.
I replaced /var/lib/pgsql/9.4/data/base I
gave it rights chown -R postgres:postgres /var/lib/pgsql/9.4/data/base

Answer 1

you need to copy completely /var/lib/pgsql/9.4/data , and not just /var/lib/pgsql/9.4/data/base
if you put symlinks on /var/lib/pgsql/9.4/data/pg_xlog, then find and transfer content too

Answer 2

stop postgres
copy all directories from /var/lib/pgsql
give postgres rights to directories and files
run postgres
well, postgress you should have the same version, not so you copied 9.1 to 9.4

I thought that all the holidays would have to work (
