### Describe the bug When pushing down the filter `column LIKE foo\_%` (i.e. all rows that start with `foo_`), the pruning predicate logic doesn't account for escape sequences in the compared string. Instead, it splits the string at the first wildcard, either "_" or "%", and uses that prefix as the literal to search for, producing a pruning predicate like `min <= 'foo\' && 'foo\' <= max`. This gives incorrect results depending on the min/max values for the row group. ### To Reproduce I will write a test that reproduces this. ### Expected behavior For `column LIKE foo\_%`, we should push down `min <= 'foo_' && 'foo_' <= max`. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
