Hello, I've got a question about operator precedence is version 9.5
Versions lower than 9.5 worked well with constructions like select a is null = b is null (it calculates if a is null, then if b is null and then compare two booleans)
But now everything is changed, and official 9.5 documentations says that IS operator has lower precedence than = operator
The thing I don't understand is the error message that I receive:
select 1 is null = 2 is null; ----------------------------- ERROR: operator does not exist: boolean = integer LINE 1: select 1 is null = 2 is null ^ HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
