For the PostgreSQL and SQL Server dialects only, adjusted the compiler so that when rendering column expressions in the RETURNING clause, the "non anon" label that's used in SELECT statements is suggested for SQL expression elements that generate a label; the primary example is a SQL function that may be emitting as part of the column's type, where the label name should match the column's name by default. This restores a not-well defined behavior that had changed in version 1.4.21 due to 🎫`6718`, 🎫`6710`. The Oracle dialect has a different RETURNING implementation and was not affected by this issue. Version 2.0 features an across the board change for its widely expanded support of RETURNING on other backends. Fixed issue in the Oracle dialect where an INSERT statement that used ``insert(some_table).values(...).returning(some_table)`` against a full :class:`.Table` object at once would fail to execute, raising an exception. Fixes: #8770 Change-Id: I2ab078a214a778ffe1720dbd864ae4c105a0691d (cherry picked from commit c8a7b67181d31634355150fc0379ec0e780ff728)
