PostgreSQL Error 22015: interval field overflow
PostgreSQL error code 22015 (interval_field_overflow) is raised when an INTERVAL value exceeds the internal storage limits of PostgreSQL's INTERVAL type, which stores values in microseconds with a theoretical range of approximately ±178,000,000 years. Although the range is enormous, certain arithmetic operations, bad string casts, or precision constraints can easily trigger this error in production. Understanding its root causes is the fastest way to fix it and keep your pipelines stable.
Top 3 Causes and Fixes
1. Arithmetic Operations Producing Out-of-Range Results
Subtracting two timestamps that are astronomically far apart can produce an INTERVAL that exceeds PostgreSQL's internal microsecond limit.
