pg_restore with --disable-triggers discards ENABLE ALWAYS

This is with postgresql version 16.4.  You can reproduce as follows:

CREATE TABLE test_table(x int);
CREATE FUNCTION test_function() RETURNS trigger AS $$ BEGIN RETURN NULL; END; $$ 
LANGUAGE plpgsql;
CREATE TRIGGER test_trigger AFTER UPDATE ON test_table FOR EACH ROW EXECUTE 
FUNCTION test_function();
ALTER TABLE test_table ENABLE ALWAYS TRIGGER test_trigger;

Checking the table:

duncan=> \d test_table
              Table "public.test_table"
  Column |  Type   | Collation | Nullable | Default
--------+---------+-----------+----------+---------
  x      | integer |           |          |
Triggers firing always:
     test_trigger AFTER UPDATE ON test_table FOR EACH ROW EXECUTE FUNCTION 
test_function()

^ Observe "Triggers firing always".


Now for the dump + restore:

pg_dump -f dump.custom -Fc --table test_table
pg_restore --data-only --disable-triggers --dbname duncan dump.custom

Checking the table:

duncan=> \d test_table
              Table "public.test_table"
  Column |  Type   | Collation | Nullable | Default
--------+---------+-----------+----------+---------
  x      | integer |           |          |
Triggers:
     test_trigger AFTER UPDATE ON test_table FOR EACH ROW EXECUTE FUNCTION 
test_function()

^ Observe that "Triggers firing always" has disappeared.

Best wishes, Duncan.
