# Purpose: To test that UDFs are replicated in both row based and   #
# statement based format. This tests work completed in WL#3629.     #
#                                                                   #
# This test is designed to exercise two of the three types of UDFs: #
# 1) UDFs via loadable libraries, and 2) UDFs with a SQL body.      #
