#                                                                              #
# Purpose:                                                                     #
#   Auxiliary script, only useful when sourced by inc/partition_check.inc.     #
#   The trigger uses new values (--> event UPDATE, INSERT only)                #
#                                                                              #
# 1. Create a trigger                                                          #
# 2. Execute a statement, which activates the trigger                          #
# 3. Check the results of the trigger activity                                 #
# 4. Revert the modifications                                                  #
#                                                                              #
