Insert helper fails on jsonb column when passed an array of booleans

repro: https://github.com/evelant/postgresjs-jsonb-array-bug

If you have a jsonb column and attempt to use the insert helper with an array of booleans for that column it will fail with

```
column "test_col" is of type jsonb but expression is of type boolean
```

When inserting/updating large objects that contain some jsonb arrays of booleans this makes the helper unusable.
