# Organization of tests:
#
#   session5-1.*: Simple tests to check the concat() function produces 
#                 correct results.
#
#   session5-2.*: More complicated tests.
#   
#   session5-3.*: Schema mismatch errors.
#
#   session5-4.*: Test the concat cases that indicate that the database
#                 was modified in between recording of the two changesets
#                 being concatenated (i.e. two changesets that INSERT rows
#                 with the same PK values).
