Description: pg_dumpall -f doesn't report error when file can't be
opened
Details:
I ran pg_dumpall on Windows Vista with the -f option. However, I wasn't
running the command as an administrator, and I specified a path that I
wasn't allowed to write to. The dump completed with no errors, and no file
was created.
Instead, I should have received an error message as soon as I ran the
command that informed me that the file I specified could not be opened for
writing.
