AFAIK, another important drawback is that you can't use it between 
different (major) versions of Postgresql, or different platforms (at 
the very least platforms with different word sizes, alignment 
constraints, byte order, etc., but also different compile-time 
settings...), as it's a binary format based on the on-disk 
representation of data. So you can't use it for transparent upgrade scenarios.

Correct me if I'm wrong.
