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

Hi Tom,

Here is a final answer to this very old thread, for the record.
You were right (as usual ;-)). It's indeed possible to register a
sequence as a "configuration table" using the pg_extension_config_dump()
function.

May be a sentence about this in the documentation would be useful. I
will try to propose something.
