Having issues searching the version 12 documentation for the string ‘IS JSON’. I gather from Google searches that this is supported in PostgreSQL but cannot find anything in the documentation. Help me understand what I’m missing and how to perform advanced searches of the documentation.
Having issues searching the version 12 documentation for the string ‘IS JSON’.
Personally I haven't seen that particular operator before, and looking at the relevant chapters of the documentation doesn't turn up anything either. Thus I conclude that contrary to your Google searches it is not supported. Trying an obvious formulation provokes an error at "json" which seems to confirm the proper absence of such an operator in the documentation.
