Explain that snake_case is the only case for column names that is compatible with the default transform functions.

+These built in transformations will only convert to/from snake_case. For example, using `{ transform: postgres.toCamel }` will convert the column names to camelCase only if the column names are in snake_case to begin with. `{ transform: postgres.fromCamel }` will convert camelCase only to snake_case.

 By default, using `postgres.camel`, `postgres.pascal` and `postgres.kebab` will perform a two-way transformation - both the data passed to the query and the data returned by the query will be transformed:
