Right.
Sorry for bothering you. As Tomas suggested, I should have
prepared the current summary.
My last e-mail summarized the current information:
https://www.postgresql.org/message-id/flat/20240722.164540.889091645042390373.kou%40clear-code.com#0be14c4eeb041e70438ab7a423b728da
It also shows that your understanding is right.
Thanks,
