Yes, the behavior of process_log_prefix_padding() is different from
strtoint() or pg_strtoint32(). For example, how the heading space
characters are handled is different. If we use the name like
pg_fast_strtoint(), we might be likely to replace the existing strtoint()
or pg_strtoint32() with pg_fast_strtoint() because its name contains
"fast", for better performance. But we should not do that because
their behavior is different.

At least for me process_padding() sounds like the function is actually
doing the padding operation. This is not what the function does.
So how about something like parse_padding(), parse_padding_format()?

I'm not sure how much it's worth doing this here. If this change is helpful
for better performance or something, IMO it's better to propose this
separately.

Thanks! Will review the patch.
