Commit Message

Interpolate typed-nil json.RawMessage as NULL

When interpolateParams=true, a typed-nil json.RawMessage (e.g. a nil
json.RawMessage stored in an interface) was interpolated as an empty
quoted string ('') instead of NULL. Inserting it into a JSON column made
the server reject it with Error 3140 (invalid JSON text).

The json.RawMessage case in interpolateParams lacked the nil guard that
the adjacent []byte case already has. Add the same guard so a nil value
is emitted as NULL, matching the server-side prepared statement path
(interpolateParams=false).

Fixes #1781
