We are running a tiny (< 1GB) Pg installation, but are starting to 
migrate over our production Oracle apps.

We run a daily Oracle dump and a daily Pg dump to /var/tmp, keeping the 
most recent four versions of each.

Nightly, we have Veritas Netbackup backup the whole filesystem to a tape 

Currently, the Oracle data directory (which also has the redo logs) is 
excluded from the UFS backup as those datafiles are 100 GB and are 
completely useless in a restore.

I have not excluded the Pg data files since I don't know what is safe to 
exclude and the files are very small.

As we migrate apps and the Pg install grows, we will need to exclude 
those data files.

Which directories/files are safe to exclude from the UFS backup?  In 
other words, what files can Pg live without and still get off the ground 
far enough to restore from a pg_dump?

Thanks in advance,
