Dandandan opened a new issue, #22253:
URL: https://github.com/apache/datafusion/issues/22253
Split out from #22247.
### Mismatch
\`replace\` with an empty search string should be a no-op.
```sql
SELECT replace('abc', '', 'x');
```
PostgreSQL:
```text
abc
```
DataFusion:
```text
xaxbxcx
```
### Expected behavior
For PostgreSQL-compatible SQL semantics, DataFusion should either match
PostgreSQL's result or raise the same class of domain/semantic error.
