There's a file descriptor leak in psql/command.c function
process_file() -- on errors it just returns without closing the file.
But since it's quitting anyway, there's no practical impact. Should I
submit a patch for this as well?

Then there are a few more cases found by null_ref (same check as the
original patch). But on closer inspection, these are false positives,
because the variable is actually modified in between dereferencing and
the NULL check.

Then there's the 'badzero' check that finds a dozen cases where
pointers are compared to a literal 0, not a NULL. This is a only a
coding style check, as far as I can tell, so I thought it's not worth
it.
