Text match filter doesn’t work with PostgreSQL filter search and gives unknown operator error.
I have PostgreSQL db with Llamaindex and I am doing filter search over it. Many operators work but text match filter doesnt work. I have newest version of Llamaindex. It gives this error:
Unknown operator: FilterOperator.TEXT_MATCH, fallback to '='

My code:

        filters = MetadataFilters(
            filters=[
                MetadataFilter(key="title", 
                operator=FilterOperator.TEXT_MATCH,        
                value="Graph RAG")
            ]
        )

Alternatively:
operator="text_match"
Rest of code is basically like https://docs.llamaindex.ai/en/stable/examples/vector_stores/postgres/
