Message-ID: <E1soZ3t-000fo2-8O@gemulon.postgresql.org> (raw)
SQL/JSON: Fix JSON_QUERY(... WITH CONDITIONAL WRAPPER)
Currently, when WITH CONDITIONAL WRAPPER is specified, array wrappers
are applied even to a single SQL/JSON item if it is a scalar JSON
value, but this behavior does not comply with the standard.
To fix, apply wrappers only when there are multiple SQL/JSON items
in the result.
