“To match” means keep two copies identical, in this case
Hello, I think what you said is right, it should be the problem. But I don't
know what to do in the lexical analysis system of plpgsql to solve this problem.

Looks suspiciously like a homework assignment.

Hello, do you mean there is a problem with this symbol itself?But so far,
there are no problems when using it.

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:
