I am confused.
currently pg_dumpall plain format will abort when encountering dbname
containing newline.
the left dumped plain file does not contain all the cluster databases data.


if pg_dumpall non-text format aborts earlier,
it's aligned with pg_dumpall plain format?
it's also an improvement since aborts earlier, nothing will be dumped?


am i missing something?
