Unique constraint violation on insert/update

duplicate key value violates unique constraint

Fixes

1.Use INSERT ... ON CONFLICT DO UPDATE (PostgreSQL upsert)
2.Use MERGE or INSERT ... ON DUPLICATE KEY UPDATE (MySQL)
3.Check for the existing record before inserting
4.Review if the unique constraint is correct for your data model
