pg_extension_config_dump() with a sequence

I wrote an extension and marked one of the tables it creates as a config table using pg_extension_config_dump(). This caused the data to be dumped and restored correctly, but the sequence attached to the PK column was not correctly set to its old value.

pg_dump: SQL command failed

pg_dump: Error message from server: ERROR:  cannot copy from sequence "sq_pk_audit_data_type"

pg_dump: The command was: COPY auditlog.sq_pk_audit_data_type  TO stdout;

pg_dumpall: pg_dump failed on database "ises", exiting
