I am planning on setting up PITR for my application.

I also have to ship them off site using a T1 so setting the time to automatically switch files will just waste bandwidth if they are still going to be 16 MB anyway.

*1. What is the effect of recompiling and reducing the default size of the WAL files?

Increased I/O

2.  What is the minimum suggested size?

16 megs, the default.

3. If I reduce the size how will this work if I try to save a document that is larger than the WAL size?

You will create more segments.
