Previously, parsing an interval with a fractional year would produce an interval that was "too precise" compared to Postgres, which we aim to be compatible with. Postgres truncates the precision of fractional years in intervals to months; we did not. This commit fixes the issue. For example, '1.1 year'::interval will become '1 year 1 month' instead of a quantity with days and hours. Release note (sql change): parsing intervals with fractional years now produces intervals with no more precision than months, to match the behavior of Postgres.

There's no more scheduled 19.2 releases so I'll just close this. It's failing bc of a TeamCity thing i think |
