Sure, but that’s not what the person responding to my original comment was suggesting :). They suggested that you serialize entire data structures (bloom filters, lists, sets, etc…) into a relational DB to get redis-like functionality out of it; I chose a list as an example to illustrate why that’s not a great option in many cases.

You’re right that managing lists in RDMSes is easy-ish, if you don’t have too many of them, and they’re not too large. But, like I mentioned in my original comment, redis really shines as a complex data structure server. I wouldn’t want to implement my own cuckoo filter in Postgres!
