RawRowMapper not mapping correctly Boolean values in Postgres 11.5 using Kotlin

[ropjov]

Description

When using the rawRowMapper and raw queries on PSQL, the boolean values are not mapped correctly, but when creating the query through query builder it works.

Environment

OS: Ubuntu
IDE: IntellIJ
Language: Kotlin 1.4
OrmLite versions:
compile group: 'com.j256.ormlite', name: 'ormlite-core', version: '5.1'
compile group: 'com.j256.ormlite', name: 'ormlite-jdbc', version: '5.1'
DB connector: compile group: 'org.postgresql', name: 'postgresql', version: '9.3-1100-jdbc4'

How to reproduce

1. Create a Postgres database and a table with the following schema

CREATE TABLE test(
    id SERIAL NOT NULL PRIMARY KEY,
   is_enabled BOOLEAN NOT NULL DEFAULT TRUE
);

2. Create its connection source in code: i.e.
   val testServiceConnection: ConnectionSource? = JdbcConnectionSource(testServiceDBString, testServiceDBUser, testServiceDBPassword)

3. Create the model:

@DatabaseTable(tableName = "test")
data class Test(
    @Generated
    @DatabaseField(generatedId = true, columnName = "id")
    var id: Int,

    @DatabaseField(columnName = "is_enabled")
    var isEnabled: Boolean
) {
    private constructor() : this(
        -1,
        true
    )
}

4. Insert two elements to the table, one true and one false

5. Create the DAO and two queries:

    private val dao: Dao<Test, Int> =
        DaoManager.createDao(ORMLiteConnections.testServiceDBORM, Test::class.java)

    fun getAll(): List<Test> {
       return userDao.queryBuilder().query()
    }

    fun getAllRaw(): List<Test> {
       val returnList: MutableList<Test> = emptyMutableList()
       userDao.queryRaw("SELECT * FROM test", dao.rawRowMapper).forEach { returnList.add(it) }
       return returnList
    }

6. Execute both and see that in the first one, the result is correct, but on the second one it is not
