Dear Hackers,

I perfectly missed mails and 8/9 was a national holiday.
I must apologize about anything. Very sorry for inconvenience.

Of cause I will try to avoid it but I can understand doing your business.

Dear Meskes,

I summarize the thread.
As you might know DECLARE STATEMENT has been added from PG14, but I
found that connection-control feature cannot be used for DEALLOCATE
and DESCRIBE statement (More details, please see patches or ask me).
But we have a question - what statement should use the associated
connection? Obviously DEALLOCATE statement should follow the linked
connection because the statement uses only one sql identifier. In
DESCRIBE or any other descriptor-related statements, however, I think
it is non-obvious because they have also descriptor-name. Currently I
made patches that includes about DESCRIBE, but I'm wondering this
approach is correct. I want you to ask your opinion about the scope of
DECLARE STATEMENT.
Coding is not hard hence I think we can fix this until the end of Sep.
if we set a policy correctly and have reviewers.

Best Regards,
