- Add `as <int_type>` to sequence creation options
- int_type can be signed or unsigned integer types, including
tinyint, smallint, mediumint, int and bigint
- Limitation: when alter sequence as <new_int_type>, cannot have any
other alter options in the same statement
- Limitation: increment remains signed longlong, and the hidden
constraint (cache_size x abs(increment) < longlong_max) stays for
unsigned types. This means for bigint unsigned, neither
abs(increment) nor (cache_size x abs(increment)) can be between
longlong_max and ulonglong_max
- Truncating maxvalue and minvalue from user input to the nearest max
or min value of the type, plus or minus 1. When the truncation
happens, a warning is emitted
