Hm. As of a year or two back, we sanitize object names in the comments
printed in the restore script, eg after
d1=# create table p (f1 int primary key);
CREATE TABLE
d1=# create table f (f1 int);
CREATE TABLE
d1=# alter table f add constraint "weird
d1"# name" foreign key (f1) references p;
ALTER TABLE
the dump output will look like
--
-- Name: f weird name; Type: FK CONSTRAINT; Schema: public; Owner: postgres
--
ALTER TABLE ONLY f
ADD CONSTRAINT "weird
name" FOREIGN KEY (f1) REFERENCES p(f1);
However, pg_restore -l didn't get the memo:
;
; Selected TOC Entries:
;
2991; 1262 46745 DATABASE - d1 postgres

195; 1259 46751 TABLE public f postgres
194; 1259 46746 TABLE public p postgres
2986; 0 46751 TABLE DATA public f postgres
2985; 0 46746 TABLE DATA public p postgres
2862; 2606 46750 CONSTRAINT public p p_pkey postgres
2863; 2606 46754 FK CONSTRAINT public f weird
name postgres
and in turn that breaks -L for such cases. I think we need to transpose
the sanitization to also happen in these code paths.
Perhaps this should have been treated as a security issue, but the
cat's out of the bag now. I think automated workflows involving -l
are pretty rare anyway.
