pg_restore into a different table structure? - postgresql

Question

I have two different databases containing a table called feed_items
Lets call them source and destination.
I want to copy some 250k rows from the source feed_items table to the destination feed_items table
Structure of source feed_items table
CREATE TABLE IF NOT EXISTS public.feed_items
(
feed_item_id uuid NOT NULL,
pubdate timestamp with time zone NOT NULL DEFAULT CURRENT_TIMESTAMP,
link character varying COLLATE pg_catalog."default" NOT NULL,
guid character varying COLLATE pg_catalog."default",
title text COLLATE pg_catalog."default" NOT NULL,
summary text COLLATE pg_catalog."default",
content text COLLATE pg_catalog."default",
author character varying(63) COLLATE pg_catalog."default",
feed_id integer NOT NULL,
tags character varying(127)[] COLLATE pg_catalog."default" DEFAULT '{}'::character varying[],
title_vector tsvector,
summary_vector tsvector,
CONSTRAINT feed_items_pkey PRIMARY KEY (feed_item_id),
CONSTRAINT fkey_feed_item_feed FOREIGN KEY (feed_id)
REFERENCES public.feeds (feed_id) MATCH SIMPLE
ON UPDATE CASCADE
ON DELETE CASCADE
)
TABLESPACE pg_default;
ALTER TABLE IF EXISTS public.feed_items
OWNER to ch_v3_root;
CREATE INDEX IF NOT EXISTS idx_feed_items_pubdate_feed_item_id_desc
ON public.feed_items USING btree
(pubdate DESC NULLS FIRST, feed_item_id DESC NULLS FIRST)
TABLESPACE pg_default;
CREATE INDEX IF NOT EXISTS idx_summary_vector
ON public.feed_items USING gin
(summary_vector)
TABLESPACE pg_default;
CREATE INDEX IF NOT EXISTS idx_tags_array
ON public.feed_items USING gin
(tags COLLATE pg_catalog."default")
TABLESPACE pg_default;
CREATE INDEX IF NOT EXISTS idx_title_vector
ON public.feed_items USING gin
(title_vector)
TABLESPACE pg_default;
CREATE TRIGGER on_insert_feed_items
AFTER INSERT
ON public.feed_items
FOR EACH ROW
EXECUTE FUNCTION public.notify_change_feed_items();
CREATE TRIGGER on_update_feed_items
AFTER UPDATE
ON public.feed_items
FOR EACH ROW
WHEN (new.title <> old.title OR new.summary <> old.summary OR new.content <> old.content)
EXECUTE FUNCTION public.notify_change_feed_items();
CREATE TRIGGER trigger_update_summary_vector
BEFORE INSERT OR UPDATE
ON public.feed_items
FOR EACH ROW
EXECUTE FUNCTION tsvector_update_trigger('summary_vector', 'pg_catalog.english', 'summary');
CREATE TRIGGER trigger_update_title_vector
BEFORE INSERT OR UPDATE
ON public.feed_items
FOR EACH ROW
EXECUTE FUNCTION tsvector_update_trigger('title_vector', 'pg_catalog.english', 'title');
Structure of the destination feed_items table
CREATE TABLE IF NOT EXISTS public.feed_items
(
id uuid NOT NULL,
author character varying(255) COLLATE pg_catalog."default",
content text COLLATE pg_catalog."default",
guid character varying(2047) COLLATE pg_catalog."default",
link character varying(2047) COLLATE pg_catalog."default" NOT NULL,
pubdate timestamp with time zone NOT NULL DEFAULT now(),
searchable tsvector GENERATED ALWAYS AS (((setweight(to_tsvector('english'::regconfig, COALESCE(title, (''::character varying)::text)), 'A'::"char") || setweight(to_tsvector('english'::regconfig, COALESCE(summary, ''::text)), 'B'::"char")) || setweight(to_tsvector('english'::regconfig, COALESCE(content, (''::character varying)::text)), 'C'::"char"))) STORED,
summary text COLLATE pg_catalog."default",
tags character varying(255)[] COLLATE pg_catalog."default" NOT NULL DEFAULT (ARRAY[]::character varying[])::character varying(255)[],
title text COLLATE pg_catalog."default" NOT NULL,
feed integer NOT NULL,
CONSTRAINT feed_items_pkey PRIMARY KEY (id),
CONSTRAINT feed_items_link_key UNIQUE (link),
CONSTRAINT feed_items_feed_fkey FOREIGN KEY (feed)
REFERENCES public.feeds (id) MATCH SIMPLE
ON UPDATE CASCADE
ON DELETE CASCADE
)
TABLESPACE pg_default;
ALTER TABLE IF EXISTS public.feed_items
OWNER to ch_api_user;
CREATE INDEX IF NOT EXISTS feed_items_pubdate_id
ON public.feed_items USING btree
(pubdate DESC NULLS FIRST, id DESC NULLS FIRST)
TABLESPACE pg_default;
CREATE INDEX IF NOT EXISTS feed_items_searchable
ON public.feed_items USING gin
(searchable)
TABLESPACE pg_default;
CREATE INDEX IF NOT EXISTS feed_items_tags
ON public.feed_items USING gin
(tags COLLATE pg_catalog."default")
TABLESPACE pg_default;
The names of a few columns have changed, the order of columns has changed and the table is assigned to a different database user. How do I pg_restore from source to destination?
