ISSUE: 6815
TITLE: Support multiple rows for DML RETURNING
DESCRIPTION:
Test verifies only basic issues related mostly to syntax and ability to get multiple rows.
Both DSQL and PSQL are tested.
Interruption of fetching process by client (and check number of affected rows) is NOT verified:
separate test will be made later (see ticket, comment by Adriano, date: 15-JUL-2021).
