## Which issue does this PR close? <!-- We generally require a GitHub issue to be filed for all bug fixes and enhancements and this helps us generate change logs for our releases. You can link an issue to this PR using the GitHub syntax. For example `Closes #123` indicates that this PR will close issue #123. --> Needed in https://github.com/datafusion-contrib/datafusion-variant/issues/26 Backport of https://github.com/apache/datafusion/pull/20628 on v53 branch. ## Rationale for this change <!-- Why are you proposing this change? If this is already explained clearly in the issue then this section is not needed. Explaining clearly why changes are proposed helps reviewers understand your changes and offer better suggestions for fixes. --> - `sqlparser-rs` currently exposes the colon operator (`:`) as a special `JsonAccess` expression. So it fails in datafusion's parsing before an `ExprPlanner` is even invoked. - Add `Operator::Colon`. Currently it's not used/implemented in datafusion. ## What changes are included in this PR? <!-- There is no need to duplicate the description in the issue here but it is sometimes worth providing a summary of the individual changes in this PR. --> - Fixes the above problem by converting `JsonAccess` to a normal binary expr, on which the `ExprPlanner` is invoked and custom parsing can be done. ## Are these changes tested? <!-- We typically require tests for all PRs in order to: 1. Prevent the code from being accidentally broken by subsequent changes 2. Serve as another way to document the expected behavior of the code If tests are not included in your PR, please explain why (for example, are they covered by existing tests)? --> Added tests. Also did a prototype of a custom `ExprPlanner` in datafusion-variant using this to convert colon operator to `variant_get` function - https://github.com/datafusion-contrib/datafusion-variant/pull/31 ## Are there any user-facing changes? <!-- If there are user-facing changes then we may require documentation to be updated before approving the PR. --> <!-- If there are any breaking changes to public APIs, please add the `api change` label. --> Add `Operator::Colon` -- This is an automated message from the Apache Git Service.
