Is there any way that works for these kind of cases?

Our update guide includes a guide for your exact use case

Doing a manual update / space constrained environments

If you are in a constrained space environment without any way to get more space you can try the following:

./launcher stop app #(or both web_only and data if that is your case)
mkdir -p /var/discourse/shared/standalone/postgres_data_new
docker run --rm \
	--entrypoint=/bin/bash \
	-v /var/discourse/shared/standalone/postgres_data:/var/lib/postgresql/13/data \
	-v /var/discourse/shared/standalone/postgres_data_new:/var/lib/postgresql/15/data \
	tianon/postgres-upgrade:13-to-15 \
	-c "apt-get update && apt-get install -y postgresql-13-pgvector postgresql-15-pgvector &&
	docker-upgrade"
mv /var/discourse/shared/standalone/postgres_data /var/discourse/shared/standalone/postgres_data_old
mv /var/discourse/shared/standalone/postgres_data_new /var/discourse/shared/standalone/postgres_data
docker run --rm -v /var/discourse/shared/standalone:/shared \
local_discourse/app chown -R postgres:postgres /shared/postgres_data #(or local_discourse/data)
./launcher rebuild app #(or first data and then web_only if that is your case)

On my tests this procedure requires less than 1x your current database size in free space.

We added this option for people who in the same situation as you. Just be sure to store a backup offsite before trying this!
