Well it looks like you have something strange going on. What data type is
car_id in each table?
     

car_id is a varchar(10) in both tables.
   

Well for some reason it's being cast to a text to do the merge.

What version of postgres is this btw? The analyzes look like 7.4?

 

Yes, this is 7.4.
