Does this just not work on bit.io or have I misunderstood what does and doesn’t work in postgresql?
The | operator works as an OR in pattern matching i.e. SIMILAR TO ‘%(0|1|2|3|4|5|6|7|8|9)%’ looks for digits in a string but & didn’t work i.e. SIMILAR TO ‘%(1&2)%’ didn’t find strings containing 1 and 2.
