   HelixDB – Open-source vector-graph database for AI applications (Rust)▲237

   Hey HN, we want to share HelixDB (https://github.com/HelixDB/helix-db/), a project a college friend and I are working on. It’s a new database that natively intertwines graph and vector types, without sacrificing performance. It’s written in Rust and our initial focus is on supporting RAG. Here’s a video runthrough: https://screen.studio/share/szgQu3yq. Why a hybrid? Vector databases are useful for similarity queries, while graph databases are useful for relationship queries. Each stores data in a way that’s best for its main type of query (e.g.…

    Embed an SQLite database in your PostgreSQL table▲180

    pglite-fusion is a PostgreSQL extension that allows you to embed SQLite databases into your PostgreSQL tables by enabling the creation of columns with the `SQLITE` type. This means every row in the table can have an embedded SQLite database. In addition to the PostgreSQL `SQLITE` type, pglite-fusion provides the `query_sqlite`` function for querying SQLite databases and the `execute_sqlite` function for updating them. Additional functions are listed in the project’s README. The pglite-fusion extension is written in Rust using the pgrx framework [1]. ---- Implementation Details The PostgreSQL…

    Pgrust, Postgres in Rust (passing 100% of Postgres regression tests)▲6

    pgrust is a PostgreSQL rewrite in Rust I've been working on with my friend Jason. It now passes 100% of PostgreSQL's regression tests and we were even able to boot pgrust off an existing PostgreSQL 18.3 data directory. You can hack on its code or try it out quickly with the WASM build on pgrust.com. It's not production ready yet. I haven't focused on performance optimized yet and it's not compatible with existing PostgreSQL extensions. I want to improve upon Postgres in many ways in the future. I wrote about some here [0], and Jason and I saw a great talk in person at PGConf.dev a month ago…
