[??????????????]

Hello everyone??


I added a ?? operator to scan.l. The sqrt function is still used internally, 
but there is a problem now, which affects the := and .. operators of the 
database.


# Description of Requirement:
1??select ?? num1; function
2??The value of num1 is required to be: [0,9223372036854775807]
3???? The operation does not allow decimals


I have now developed this feature on the PostgreSQL 14.0 kernel! But it affects 
the original function of the database:


# Affected place
1?? := assignment operator
2?? Operator in 1..10


# Recurring problem
1??make check

sqrt_bigint.patch
