Does this make sense? Filtering on array values is well defined. I don't see why other operands should not be supported.

I thought I would make the implementation more complete in #271, but that still needs quite a lot of work. Merging this instead as it is pretty compact change with minimal impact.

This PR adds
eqquery filter support for columns mapped with theJSON_LISTvalue type, allowing callers to check whether a string value is an element of the JSON array stored in a given column. The implementation introduces a protectedvisitJsonListAssertionhook inMappedSQLQueryFilterVisitorthat is overridden in each vendor handler using the appropriate database-native JSON function — PostgreSQL uses theJSONBcontainment operator, MySQL usesJSON_CONTAINS, Oracle usesJSON_EXISTS, and MSSQL usesOPENJSON. Any operator other than equals on a JSON_LIST column will throwUnsupportedOperationException.
