This could be greatly simplified.

• The first condition is unnecessary. It's just a special case of 2nd condition and thus, can be completely removed.
• The third condition can be simplified. The last expression in the condition (a != 1 && b == 1 && c != 1) will only be evaluated when earlier expressions in the condition failed.
  Therefore, no need to check if a and c are 1 or not. Third condition should just be (a === 1 || c === 1 || b === 1).

Fixed, thanks

Just a typo here:

"A row should ebe created on each break"

I belive, it should be:

"A row should be created on each break"

I just used it (with PostgresSQL 9.6), and it worked.

Mindfuck lol
