autoincrement in PostgreSQL

Hello!

I found that autoincrement flag on the column is ignored in PostgreSQL 
backend. So I created a patch. Here's new columns.vm I created for 
PostgreSQL.

====================================================
#foreach ($col in $table.Columns)
    #set ( $type = $col.Domain.SqlType )
    #set ( $size = $col.printSize() )
    #set ( $default = $col.DefaultSetting )
    #set ( $autoIncrement = $col.isAutoIncrement() )
    #if ( $autoIncrement )
        #if ( $type == "INT8" )
            #set ( $type = "SERIAL8" )
        #elseif ( $type == "INT" )
            #set ( $type = "SERIAL4" )
        #elseif ( $type == "INT4" )
            #set ( $type = "SERIAL4" )
        #end
    #end
    #set ( $entry = "$col.Name $type $size $default $col.NotNullString," )
    $strings.sub($strings.collapseSpaces($entry)," ,",",")
#end
====================================================

Can this patch be commited to CVS repository?
