[svn at svn.open-ils.org]

Author: miker

New Revision: 17634

Added:
   trunk/Open-ILS/src/sql/Pg/upgrade/0393.schema.perm-id-change-i18n-protection.sql
Modified:
   trunk/Open-ILS/src/sql/Pg/002.schema.config.sql
   trunk/Open-ILS/src/sql/Pg/006.schema.permissions.sql
Log:
we need to move permissions around for a Great Renumbering, but i18n is not protected by fkeys.  this provides infratructure for maintaining i18n values that already exist in a db, and an example usage on permission.perm_list
