There are no bit operations on values larger than 64 bits, so such literals should be rejected. > (6) Do not support hexadecimal integer literals for casts and affinity > coercions. There is a compatibiliy constraint: parsing hexadecimal values out of strings would change the documented behaviour of casts and coercions: | When casting a TEXT value to INTEGER, the longest possible prefix of | the value that can be interpreted as an integer number is extracted | from the TEXT value and the remainder ignored. So (6) appears to be the only viable choice.
