Answer 1

PostgreSQL 9.4

SELECT column_name , data_type ,character_maximum_length  FROM information_schema.columns WHERE table_schema = 'your_schema' AND table_name   = 'your_table';

Answer 2

From Phalcon you can use Model metadata.

$manager = new Manager();
$order = new Order();

$metadata = $model->getModelsMetaData();

var_dump($metadata->getDataTypes($manager));

You will get and array with each column name and the type as an integer.

array (size=3)
  'col1' => int 0
  'col2' => int 2
  ...
  'coln' => int 2

The integer is one of the TYPE_* constants from \\Phalcon\\Db\\Column .
