"The more likely suspect is a foreign key conflict. 

Are both transactions inserting/updating rows that could reference 

the same row(s) in a master table?" - Tom Lane

This is exactly the case (in my case) - several connections tries to insert rows in the same table... but some columns are referenced to settings tables... and there is possibility that two rows what we want to insert reference the same row in settings table...
