Does it mean that there was an error in "SELECT ..." and hence internally postgres executed ROLLBACK??  


If there was an error you would see an error message.  Plus, PostgreSQL doesn’t just internally issue a rollback on its own.  That said I’m not sure what is being shown, or rather where the “execute” stuff comes from.

Given that PostgreSQL isn't throwing the error, I'd suggest the rollback is from a decision in the front-end application layer.
