This is to announce the first, Alpha, release of Veil, a database security add-on for Postgres. It allows databases to be created with efficient row-level access controls; different users have access to different subsets of data.
Veil is hosted on pgfoundry at http://veil.projects.postgresql.org/ Documentation is here: http://veil.projects.postgresql.org/curdocs/index.html If there is sufficient interest, I would ultimately like Veil to be added to contrib - we will have to see how things pan out. I am announcing this to the postgres hackers list as I hope for review comments from a qualified community. All comments will be welcomed. If you would like somewhere controversial to start your review, take a look at veil_shmem.c which hooks into the postgres shared memory subsystem. Since I was unable to dynamically assign a LWLock using LWLockAssign (none available), I have fairly arbitrarily overloaded the use of existing LWLocks. When the flames die down perhaps we can discuss making a small number (one would be enough for me) of LWLocks available. Thank you. __ Marc Munro
