If the vars argument is specified, it provides an object containing named variables to be substituted into a jsonpath expression.
The jsonb_path_exists, jsonb_path_match, jsonb_path_query, jsonb_path_query_array, and jsonb_path_query_first functions have optional vars and silent arguments. In PostgreSQL, path expressions are implemented as the jsonpath data type and can use any elements described in Section 8.14.6. There is a note a bit down the page that hints at potential names, as they seem to be shorthand for corollary functions with some presets : We have the following JSON functions such as jsoneach (), jsonobjectkeys (), jsontypeof (), etc. The -> operator Returns JSON data in the form of a key. PostgreSQL provides the two native operators to work with JSON data.
If the result is not Boolean, then null is returned. If JSON data is incorrect, then it will throw an error. Only the first item of the result is taken into account. In CockroachDB, the JSONB / JSON data type is similar in behavior to the JSONB data type in. ‘’::jsonb ‘$.a ? > the result of JSON path predicate check for the specified JSON value. In PostgreSQL, JSONB and JSON are two different data types. Right Operand JSON path return any item for the specified JSON value? They are defined in the docs in table 9.45
