To get around this same problem, I created a base table from which all
other tables were inherited. Doing this allows for you to query on 1
table, or all data easily.
i.e.
CREATE TABLE wwwlogs (id INT4, url TEXT);
CREATE TABLE wwwlogs_041801 INHERITS (wwlogs);
CREATE TABLE wwwlogs_041701 INHERITS (wwlogs);
HTH...
