Array question

Hi all!I, probably, have really simple question, but I can't go further. I
have two tables: one is empty like
+----------------------------------+----------------------------------+-------+
|              Field               |              Type                |
Length|
+----------------------------------+----------------------------------+-------+
| home phone number                | int4[]                          
|   var |

and another one full like

+----------------------------------+----------------------------------+-------+
|              Field               |              Type                |
Length|
+----------------------------------+----------------------------------+-------+
| first                            |  int4                           
|      4|
| second                           |  int4                           
|      4|
| third                            |  int4                           
|      4|


I need to put all elements from second table into a first one. So each
string in
second table becomes a string in a first one, so firts colun becomes a
first 
array element in first table second is second and so on. I tried several
queries
in order to do this, but failed. Can anyone help?Thank you.
