Yes I have indexes an all join fields. The tables have around 30 columns each and around 100k rows. The database is vacuumed every hour.

Just to chime in, VACUUM != VACUUM ANALYZE. ANALYZE is what updates database statistics and affects query planning. VACUUM alone does not do this.

 Do you have an index on report.id_order ? Try creating an index for
 it if not and run a vacuum analyze on the table to see if it gets
 rid of the sequence scan in the plan.
