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
