This pr rewrites GpuRLike to GpuStartsWith for a special case with a hacky approach.
A general way will be to change
RegexParserinstead of string when overriding.And the rewrite is actually wrong, we can't rewrite
rlike abc(.*)tostartsWith abcbecause the pattern can occur anywhere in the string. Onlyrlike ^abc(.*)can be rewritten. I did it intentionally wrong specifically for a customer's sql.
