Hi Boris,
I reviewed and tested the latest v15 patch for the pgbench faster data
generation modes.
My testing results
- Reproduced the existing behavior before applying the patch using '-I
dtgG', where both client-side and server-side data generation were
executed.
- Applied the v15 patch successfully and built pgbench without errors.
- Re-ran the same test after applying the patch.
- After the patch, pgbench reports the warning: 'More than one type of
data initialization is requested'.
- Both requested initialization modes were still executed successfully.
- The test completed successfully without errors.
Is the warning for multiple data-generation modes already covered by
the existing regression tests?
Based on my testing, the patch works as expected for the tested scenario.
Regards,
solai
