Works for me:
regression=# create table stats_http_downloads (day int, filerelease_id int);
CREATE
regression=# create table stats_ftp_downloads (day int, filerelease_id int);
CREATE
regression=# SELECT * FROM (stats_http_downloads sh
regression(# FULL OUTER JOIN stats_ftp_downloads sf USING (day,filerelease_id));
day | filerelease_id
