enviroment/release)

in fact , im not using it for backups, but during the evolutionary phase of 
development. we have a very short cycle, XP style, and we find convenient to be 
able to dump the db to textfiles, 
-either to preserve the data in case of break of  the schema ( and we can at 
least edit by hand the existing data),
- or to prepare test data, especially when the (editing) front end is not ready 
for inputing.

any comments ?
if u have any idea on adapting schema more automatically, ure most welcomed !
