Hi Bill,
thanks for your answer.

It would be great if we could reveal an application error.
Whole transactions I've already posted (in postgres log: log_min_duration_statement=0).
Nothing suspicious yet:
- both sessions COMMIT/ROLLBACK before BEGIN
- both sessions run the same SQL statements
- deadlock: FIRST statement of both transactions
- deadlock: update single table, same row, column without any constraints (WHY?)
- no statements of other sessions executed in between
Any idea?
thanks, Andrej
