pg_dump inside the container failed with "could not open output file C:/Users/.../Temp/studioflow_migration_....dump" - Git Bash/MSYS was rewriting the /tmp/... argument into a Windows path before handing it to docker.exe, even though it's meant to be interpreted inside the Linux container. MSYS_NO_PATHCONV=1 stops that translation.
