PG throws could not resize shared memory segment error

[Gunnar (Gunnar Helliesen)]

You should raise the limit when launching the postgres container by including the --shm-size=1g parameter.

We’ll look at fixing this in the launcher.

(or as the link suggests, disable parallelism in pg10 with max_parallel_workers_per_gather = 0)

Thanks. How would I do either of those? I searched, found this post (Starting Discourse on a Specific Docker Network) and following the example added the following line to my app.yml:

docker_args: "--shm-size=1g"

Then ran launcher rebuild app. That didn’t make any difference though, shm is still 64M inside the container.

Thanks,
Gunnar
