AcademySoftwareFoundation/OpenCue#1199 has a full description of the issue.

Over on the OpenCue project we use embedded-postgres for unit tests.

Basically we are seeing strange results from SUM(bigint) on arm64+Docker where the result is wildly incorrect.

• Issue does not occur on other architectures.
• Issue does not occur when running directly on M1 -- only in Docker.
• I've tried a few different base images (gradle, almalinux) and that doesn't seem to change the result.
• I've tried a few different Postgres versions -- 11, 12, 14, 15 -- same issue on all of them.
• I haven't been able to reproduce the issue using the standard postgres Docker image.
• Changing our queries to SUM(CAST(bigint as numeric)) fixes the issue.

Our build.gradle.

Any ideas here?
