Module json_path 

SQL/JSON path query compiler and scalar UDFs SQL/JSON path query functions (F-SCHEMA-012).

Implements a basic JSON path compiler and two scalar UDFs:

• jsonb_path_exists(jsonb, path_text) → boolean
• jsonb_path_match(jsonb, path_text) → boolean

The path language supports a PostgreSQL SQL/JSON subset:

• $ — root element
• .key — object member access
• [n] — array element by index
• [*] — wildcard array elements

JsonbPathMatchUdf

jsonb_path_match(jsonb, path_text) → boolean
