Seems to me that your relationships are a bit off. At first i thought that Sessions_Metadata was a cross reference between Users and Sessions. But it is not. Instead, it is extra info for a session. Now, if this were my project, i would only have two tables: Users and Sessions. It seems to me that everything in Sessions_Meta data relates to a session, therefore, why not just put those attributes in the Sessions table? 

sessions
   Column    |          Type          | Modifiers 
-------------+------------------------+-----------
 id          | character(32)          | not null
 a_session   | text                   | 
 username    | character varying(40)  | 
 create_date | character varying(100) | 
 expire      | character varying(100) | 
 query_id    | character varying(50)  |
It will greatly simply your task. Also ... why are you using a character type for the primary key? You should be using an "auto-incremented" integer, preferably unsigned. Likewise, you should also be using the same for your primary key in the Users table.

UPDATE:
I think that is correct, CassJ.
