DatabaseTableSchemaRegistry improvement to handle BIT/Boolean Type

The issue stems from the fact that for the PostgreSQL JDBC driver, the Boolean type is mapped to java.sql.Types.BIT, not BOOLEAN. This causes the line columnResultSet.getInt("DATA_TYPE") to return -7, which corresponds to BIT, and DataTypeUtils.getDataTypeFromSQLTypeValue(dataType) to return null, leading to a null pointer exception.
