non-existent user "28"
Hi,
when I pg_dump my database, I get lines like:
GRANT SELECT on "tablename" to "28";
When I restore from the dump file, I get errors:
ERROR: aclparse: non-existent user "28"
The dump file does contain grants for the real users which exist in the
database, and I've checked pg_shadow, and there is no user 28.
I'm not sure how the database got in this state - would this happen when I
drop & recreate a user? Is there something I can do about this? I couldn't
see where in the system tables the permission info is stored.
Thanks,
Tamsin

Yes. There's no crosscheck to see if you still have active GRANTs for
the user being deleted. (Which is bad but that's how it is at the moment.)

relacl column of pg_class.
My advice would just be to ignore the errors on restore... that's about
the easiest way to get rid of the dead grants while keeping the good ones.
