Description:

I'm using pg_dump to dump my database version 12.5 (RDS), pg_dump version
12.6  but I have a the following table 

CREATE TABLE public.projects_historydata
(
    id bigint NOT NULL DEFAULT
nextval('projects_historydata_id_seq'::regclass),
    value double precision NOT NULL,
    value_at timestamp with time zone NOT NULL,
    var_id integer NOT NULL,
    created timestamp with time zone NOT NULL,
    CONSTRAINT projects_historydata_pkey PRIMARY KEY (id),
    CONSTRAINT projects_historydata_var_id_21f99477_fk_projects_var_id
FOREIGN KEY (var_id)
        REFERENCES public.projects_var (id) MATCH SIMPLE
        ON UPDATE NO ACTION
        ON DELETE NO ACTION
        DEFERRABLE INITIALLY DEFERRED
)

WITH (
    autovacuum_enabled = TRUE
)
TABLESPACE pg_default;

ALTER TABLE public.projects_historydata
    OWNER to wedbmaster;

GRANT SELECT ON TABLE public.projects_historydata TO read_only_user;

GRANT SELECT ON TABLE public.projects_historydata TO readaccess;

GRANT ALL ON TABLE public.projects_historydata TO wedbmaster;
-- Index: projects_historydata_db9d0193

-- DROP INDEX public.projects_historydata_db9d0193;

CREATE INDEX projects_historydata_db9d0193
    ON public.projects_historydata USING btree
    (var_id ASC NULLS LAST)
    TABLESPACE pg_default;
-- Index: projects_historydata_var_id_value_at_idx

-- DROP INDEX public.projects_historydata_var_id_value_at_idx;

CREATE INDEX projects_historydata_var_id_value_at_idx
    ON public.projects_historydata USING btree
    (var_id ASC NULLS LAST, value_at ASC NULLS LAST)
    TABLESPACE pg_default;

-- Trigger: after_insert_projects_historydata_trigger

-- DROP TRIGGER after_insert_projects_historydata_trigger ON
public.projects_historydata;

CREATE TRIGGER after_insert_projects_historydata_trigger
    AFTER INSERT
    ON public.projects_historydata
    FOR EACH ROW
    EXECUTE FUNCTION public.projects_historydata_delete_master();

-- Trigger: before_insert_projects_historydata_trigger

-- DROP TRIGGER before_insert_projects_historydata_trigger ON
public.projects_historydata;

CREATE TRIGGER before_insert_projects_historydata_trigger
    BEFORE INSERT
    ON public.projects_historydata
    FOR EACH ROW
    EXECUTE FUNCTION public.projects_historydata_insert_child();

this table make references to the sequence projects_historydata_id_seq 
-- SEQUENCE: public.projects_project_id_seq

-- DROP SEQUENCE public.projects_project_id_seq;

CREATE SEQUENCE public.projects_project_id_seq
    INCREMENT 1
    START 1
    MINVALUE 1
    MAXVALUE 9223372036854775807
    CACHE 1;

ALTER SEQUENCE public.projects_project_id_seq
    OWNER TO wedbmaster;

GRANT SELECT ON SEQUENCE public.projects_project_id_seq TO read_only_user;

GRANT ALL ON SEQUENCE public.projects_project_id_seq TO wedbmaster;

At the moment to do a pg_dump the pg_dump doesn't make the script for the
sequence, then the restore fail to create the table.

Please see that the id value for the table (the value handle by the
sequences is not an integer is biginteger)
