# 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 #
