Re: Can't restart Postgres

Yes, that’s the correct sequence of scripts.  And no there’s not anything really helpful in the system logs.  

I’m thinking that at this point I need to approach this problem as more of a disaster recovery.  There was a full pg_dumpall  file that was deleted and cannot be recovered so I need to recover the data from the /var/lib/postgresql/9.4/main directory.  I believe this is called a file level recovery.  I assume I need to use a fully functional, same version PG (on another machine?) to create a full dump of the data directory.  Once I have this I can re-install Postgres on the initial server and read the databases back into it. 

Any advice on how to best go about this?  The official documentation seems a bit thin:

https://www.postgresql.org/docs/9.4/static/backup-file.html

I’ve only worked with normal (pg_dump, pg_dumpall) backups in the past.
