Re: Temporal databases

Hi Philippe,
Have a look at the post I made to the pgsql-sql list I made on 6th November 
2007 (day before you posted this). It contains alot of stuff for temporal 
tables within Postgres.
However temporal tables (when done properly) are a very complex subject at the 
best of times. It depends how much you want to integrate them. A good place 
to start is Joe Celko's book "SQL For Smarties" and Richard Snodgrass' 
book "Developing Time-Oriented Database Applications in SQL" - this book is 
no longer in print, but is downloadable (for FREE!) from: 
http://www.cs.arizona.edu/~rts/tdbbook.pdf
Richard Snodgrass is one of the leading experts in the field. I warn you - the 
book is heavy going - but so worth it!!
