Well, here is one way.  In your script issue the command:

   psql -c "\d" -o filename database_name

depending on your scripting language you may need to wrap the command around
some other command such as:

   system ("psql -c \"\\d\" -o filename database_name");

in perl.  Now with this approach your script will then need to read in the file
created by the -o switch.  If your in perl you could do something like:

   open(COMMAND, "psql -c \"\\d\" database_name|")
   while (<COMMAND>)
   {
      print $_;
     <YOUR CODE GOES HERE>
   }

to not generate a file, and read in the standard output of the psql command.
In the the Korn shell you could do:


   psql -c "\d" database_name| while read LINE
   do
       echo $LINE
      <YOUR CODE GOES HERE>
   done

Hope this helps...james
