[I] Incorrect regex pattern in regex_replace_posix_groups [datafusion]
shivbhatia10 opened a new issue, #19766:
URL: https://github.com/apache/datafusion/issues/19766
### Describe the bug
The `regex_replace_posix_groups` method should replace patterns like `\4` with `${4}` but it's using the pattern `(\\)(\d*)` instead of `(\\)(\d+)`.
### To Reproduce
I added a test in the fix PR which replaces some pattern with "\\", currently this produces "${}" which is how I came across this bug.
### Expected behavior
Should just replace the pattern with "\"
### Additional context
