Re: BUG #6682: pg_dump and sequence values of serial columns for extension configuration tables

I think the way to make that happen is to also register the sequence as
a configuration table of the extension.  It's not clear to me that that
should happen by default; it would depend a lot on how the extension
designer intends to manage modifications of the table.

This test proves nothing of the kind.  Please read the error message:
ERROR:  pg_extension_config_dump() can only be called from an SQL script executed by CREATE EXTENSION
You have to do it in the extension's script.
