davical/dba/patches/1.2.3.sql

-- Add some more cascading updates and deletes.
-- For databases created before PostgreSQL 8.0.

-- I screwed up with version 0.9.6.1 and 0.9.6.2 in that the davical.sql
-- file specified them as version 1.2.2 when in reality they were version
-- 1.2.4 so we are going to clean that up here...
