Adrian, Jim: thanks a lot for your help. I'll replay my logs on a Windows machine very similar to the one that was hosting my db and see how it goes before I make a pg_dump for Linux.
I have a base backup and archive logs from a Windows 7 PGSQL 9.3 install. The machine OS disk started to show signs of failure so I replaced it and now I want to switch for a Linux system.
My question is: will I be able to play my archive logs and point-in-time recover on the Linux machine?
No. The machines have to be the same OS/architecture.
That would spare some time rebuilding a Windows machine, recovering my db, and dumping for a Linux box.
