There seems to be a small bug in the pg_strtointXX functions in the

End with a backslash and a period on a line by itself, or an EOF signal.

Fixed in new patch. I moved the "require at least one digit" checks
after the loops over the digits, to make it easier to write one check
for all bases.
This patch is also incorporates your changes to the digit analysis
algorithm. I didn't check it carefully, but all the tests still pass. ;-)
