The "does not exist" error in object_aclmask_ext() was written as ereport(), suggesting that it is user-facing. This is problematic: get_object_class_descr() is meant to be for internal errors only and does not support translation. For the has_xxx_privilege functions, the error has not been user-facing since commit 403ac226ddd. The remaining users are pg_database_size() and pg_tablespace_size(). The call stack here is pretty deep and this dependency is not obvious. Here we can put in an explicit existence check with a bespoke error message early in the function. Then we can downgrade the error in object_aclmask_ext() to a normal "cache lookup failed" internal error.
