display query results

I am trying to learn postgresql with psql - using FreeBS D7.0,
postgresql 8.3.3 php 5.2.6, apache 2.2.9

How can I echo or print on screen the results; all I get from this code
is this:
Resource id #3
item_idglossary_idnamedescription
which is the field names run together

I am expecting to see several long text sentences.

Here is the snippet and the connection does work and the database is
there and functioning.

$db = pg_connect("host=localhost port=5432 dbname=med user=med
password=0tscc71");

if (!$db)
{
die("Could not open connection to database server");
}

// generate and execute a query
$query = "SELECT description FROM glossary_item WHERE
name='Alcohol'";
$result = pg_query($db, $query) or die("Error in query: $query.
" . pg_last_error($db));

// Print result on screen
echo "$result";

pg_close($db);

What am I doing wrong?
