Fix incorrect return value for pg_size_pretty(bigint)
pg_size_pretty(bigint) would return the value in bytes rather than PB
for the smallest-most bigint value. This happened due to an incorrect
assumption that the absolute value of -9223372036854775808 could be
stored inside a signed 64-bit type.
Here we fix that by instead storing that value in an unsigned 64-bit type.
This bug does exist in versions prior to 15 but the code there is
sufficiently different and the bug seems sufficiently non-critical that
it does not seem worth risking backpatching further.
