configure existing block leads to database error

Using postgres and apache2, I made a simple block with 1 line of text. I then went back to edit the block and add a style to to the text, but get this error at the top, with no data for the block in the input boxes below:

    * warning: pg_query() [function.pg-query]: Query failed: ERROR: column reference "title" is ambiguous in /home/web/html/includes/database.pgsql.inc on line 125.
    * user warning: query: SELECT bx.*, title FROM boxes bx INNER JOIN blocks bl ON bx.bid = bl.delta WHERE module = 'block' AND bid = 2 in /home/web/html/includes/database.pgsql.inc on line 144.

I have tinymce and views module installed, and nothing else.
