Rails - Mar 2006 - Strange Postgres Behaviour with Session Variables

Can someone explain why Rails is querying the Postgres database every 
time I retrieve a session variable??  The query is to determine the 
attributes of the model object I guess and looks like this: "SELECT 
a.attname, format_type(a.atttypid, a.atttypmod), d.adsrc, a.attnotnull 
FROM pg_attribute a LEFT....".

Like I said, this SELECT only occurs when I load a variable such as: 
@value = session[:value]

The behaviour seems wrong since it wasn''t occurring using MySQL 
previously.

Thanks,
Tyler
