pgsql: Improve conversions from uint64 to Perl types.

Improve conversions from uint64 to Perl types.

Perl's integers are pointer-sized, so can hold more than INT_MAX on LP64
platforms, and come in both signed (IV) and unsigned (UV). Floating
point values (NV) may also be larger than double.

Since Perl 5.19.4 array indices are SSize_t instead of I32, so allow up
to SSize_t_max on those versions. The limit is not imposed just by
av_extend's argument type, but all the array handling code, so remove
the speculative comment.
