[PyGreSQL] Patch to add read support for integer arrays

[Mikko Korkalo]

Hi,

I figured pgdb.py (version 1.33) didn't have support to read int2[] and 
int4[] types, so I added support for it. I don't know if this was in the 
CVS/SVN tree already.

When reading data, int2[] and int4[] are now converted to a list 
containing ints, instead of passing them as str, i.e. '{ 1, 2 }' to the 
program.

I don't know if this is the correct way to do this.
Maybe all of the array types should be handled at once?
