The "BIGINT(20)" specification isn't a digit limit.  It just means that when
the data is displayed, if it uses less than 20 digits it will be left-padded
with zeros. 2^64 is the hard limit for the BIGINT type, and has 20 digits
itself, hence BIGINT(20) just means everything less than 10^20 will be
left-padded with spaces on display.  This is kind of getting off topic
though, so...
