Handling Null Values in Postgres

Re:Handling Null Values in Postgres by mcdoker18 on Thursday March 05, 2020 @03:40PM (#22497923)

Can someone explain the meaning to use 'x == NULL' expression? Why does not PostgreSQL prohibit usage of this expression?

It is valid syntax, you are comparing an "x" with "no value" and result will be "no value"

I know that it's a valid expression, but are there any use cases for it?
