LatticeDB looks good, just curious how useful is duckpgq

duckpgq is great. I'd say the tl;dr is duckpgq if you have tables you want to traverse like a graph sometimes, latticedb when graph traversal is the primary mechanism of querying.

One of the motivating use cases for me was experimenting with agentic memory. I use latticedb as the backing data store. Finding related memories is traversing the graph (kind of like graph RAG).
