主题: 回复： BUG #16102: Table can't be drop on PostgreSQL 10.09 if the table was created from PostgreSQL 10.10
Hello,
Thanks for the reply. I understand this is an issue really sounds strange.
So, form document it saying that it should be not problem when switching between minor release.
Will you assign someone take to look this issue? Do you need the full script? It's like 100% reproduce.
BRs,
Fan Lilu

I agree and believe that we document this compatibility policy somewhere. But I found such description in docs: https://www.postgresql.org/docs/current/upgrading.html
> Minor releases never change the internal storage format and are always compatible with earlier and later minor releases of the same major version number. For example, version 10.1 is compatible with version 10.0 and version 10.6. Similarly, for example, 9.5.3 is compatible with 9.5.0, 9.5.1, and 9.5.6.
Seems opposite.
