pg_extension_config_dump() function and sequences

Hi all,

The page "Packaging Related Objects into an Extension" has a third
chapter dealing with "Extension Configuration Tables". A final paragraph
would be useful to explain that:

The pg_extension_config_dump() function can also register sequences, so
that the current properties of the registered sequences are saved by
pg_dump and later restored. The function can support sequences either
explicitely created with an ALTER SEQUENCE statement or implicitely
created when a table contains SERIAL or BIGSERIAL columns. Note that the
sequences associated to SERIAL or BIGSERIAL columns of a configuration
table need to be registered using the pg_extension_config_dump()
function if one wants to restore the properties they had at pg_dump time.

Sorry for my English. This has to be probably reworded a bit.

Best regards.
