The following documentation comment has been logged on the website:

Description:
For the formatting functions, which convert between a string and a type like
date, timestamp or number, there should be a description about the behaviour
of i.e. to_date(input, mask) in case of invalid, not convertable input.
I expected a return value of NULL and got a execution error.
