> Here's one concept of heavy vs light: I have often wished I could just email a small Pg db to a colleague. In the same way I can just attach a single file to an email and transmit an entire SQLite DB. The closest to this I've gotten is being able to run MySQL/MariaDB/PostgreSQL/other solutions in containers locally and sending archived data directories, with which they can be launched anywhere else locally, or on server. I actually had a blog post about how that looks on my servers for other applications: https://blog.kronis.dev/articles/how-i-migrate-apps-between-servers-in-2021 https://blog.kronis.dev/articles/how-i-migrate-apps-between-... For PostgreSQL, it could look like: 1. run PostgreSQL in a container, e.g. https://hub.docker.com/_/postgres , use a bind mount for the data directory, /var/lib/postgresql/data 2. once you want to share, use tar/something else to archive the local bind mount directory 3. send the archive and the command to run the container through e-mail or whatever else you prefer And on the receiving end: 1. receive the run command and attachment 2. unarchive the data directory into a folder 3. run the container with the provided command It's not perfect, but it's one of the more portable methods I've found (though there are file system issues between Linux and Windows sometimes, like when running PHP apps).
