# Tests are organised as follows:
#
# collate3.1.* - Errors related to unknown collation sequences.
# collate3.2.* - Errors related to undefined collation sequences.
# collate3.3.* - Writing to a table that has an index with an undefined c.s.
# collate3.4.* - Misc errors.
# collate3.5.* - Collation factory.
#

#
# These tests ensure that when a user executes a statement with an 
# unknown collation sequence an error is returned.
