#
# 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
