Marios Trivyzas 3f7cae3f0d SQL: Implement GREATEST and LEAST functions (#35879) ... Add GREATEST(expr1, expr2, ... exprN) and LEAST(expr1, expr2, exprN) functions which are in the family of CONDITIONAL functions. Implementation follows PostgreSQL behaviour, so the functions return `NULL` when all of their arguments evaluate to `NULL`. Renamed `CoalescePipe` and `CoalesceProcessor` to `ConditionalPipe` and `ConditionalProcessor` respectively, to be able to reuse them for `Greatest` and `Least` evaluations. To achieve that `ConditionalOperation` has been added to differentiate between the functionalities at execution time. Closes: #35878		2018-11-26 18:21:36 +01:00
