port/snprintf(): fix overflow and do padding
Prevent port/snprintf() from overflowing its local fixed-size
buffer and pad to the desired number of digits with zeros, even
if the precision is beyond the ability of the native sprintf().
port/snprintf() is only used on systems that lack a native
snprintf().
Reported by Bruce Momjian. Patch by Tom Lane. Backpatch to all
supported versions.
