The ->> operation in postgresql does not work properly

[offSwitch]

select visit_hour,json_array_elements(into_sex_json)->>'name',json_array_elements(into_sex_json)->>'value' from period_market

The problem here is that JSqlParser does only support:

column ->> literal

a function as a first "parameter" is not supported. Something you want to provide. PRs are welcome.

I'm using the latest version 4.6 and this problem seems not solved yet.
Would it be possible to be fixed in the future?

Unfortunately, allowing Function() is not possible as it will break performance reason. I think, this one is beyond any refactoring and tricks. A new and clean Grammar would be needed to achieve that.

Thank you for your reply.
I'll check my code to see if it can be refactored.

PR #1745 allows Function() ->> Literal as long as the Function is simple (no nested expressions as parameters).
