###############################################################################
#
# Basic test to confirm the correct behavior when executing SAVEPOINT,
# ROLLBACK TO and RELEASE SAVEPOINT commands
#
# The execution of SELECT guarantee the correct values on TABLE after process
# SAVEPOINT commands
#
# Test:
#   0. Create a table to insert data
#   1. Create a transaction and insert values and savepoints (S1, S2, S3, S4)
#   2. Release savepoint S4
#   4. Rollback to a savepoint S2 and verify that savepoint S3 disappeared
#   5. Insert more values and rollback to S2 to verify that rollback don't
#   remove savepoint
#   6. Check the multitable update on 'rollback to savepoint' is proper.
#   7. Clean-up
