A bit meta on my part, but I'd recommend referencing the version specific URLs from the PostgreSQL documentation when backing up a quoted claim. Your quote will referenceable now, but anyone seeing it later may see different number or the statement might be omitted from whatever the "current" version is in the future.

So instead of:

https://www.postgresql.org/docs/current/features.html

I'd recommend:

https://www.postgresql.org/docs/15/features.html
