"""Regression: SQL avg/extract "hours" aggregates must serialize as JSON numbers.
|
||
|
|
|
||
|
|
``EXTRACT(epoch ...)`` returns ``numeric`` on PostgreSQL 14+, which asyncpg
|
||
|
|
surfaces as a ``Decimal``. A ``Decimal`` serializes to a JSON *string*, so the
|
||
|
|
panel's ``avg_cycle_hours.toFixed(1)`` (and the other hours fields) threw
|
||
|
|
``toFixed is not a function`` against the live deploy. ``_as_hours`` coerces to a
|
||
|
|
real ``float`` so the field is always a JSON number.
