operations (INSERTs and UPDATEs) in the application which take more time to complete, hence this particular flow has been changed into a Java Thread so it will not wait (block) for the complete database operation to be completed. My problem is, if more than 1 user comes across this particular flow, I'm facing the following error thrown by PostgreSQL: org.postgresql.util.PSQLException: ERROR: deadlock detected Detail: Process 13560 waits for ShareLock on transaction 3147316424; blocked by postgresql deadlock detected process 13566. Process 13566 waits for ShareLock on transaction 3147316408; blocked by process 13560. The above error is consistently thrown in INSERT statements. Additional Information: 1) I have PRIMARY KEY defined in this table. 2) There are FOREIGN KEY references in this table. 3) Separate database connection is passed to each Java Thread.

The random interval is necessary so that the colliding transactions don't continuously keep bumping into each other, causing what is called a live lock - something even nastier to debug. Actually most complex applications will need such a retry mechanism sooner or later when they need to handle transaction serialization failur
