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.
