orioledb
OrioleDB – building a modern cloud-native storage engine (... and solving some PostgreSQL wicked problems)
Postgres users need to deal with the infamous transaction ID wraparound, and the not-so-famous MultiXact member exhaustion. OrioleDB is tackling these issues, but it's still years until it reaches the maturity of MySQL's InnoDB.

Project mention: Ask HN: What are you working on (September 2024)? | news.ycombinator.com | 2024-09-29
I'm extending Postgres with the GraphBLAS/SparseBLAS APIs for sparse and dense linear algebra operations directly in SQL with OneSparse. Like JSON/JSONB did for unstructured data, OneSparse does for matrices, vectors and linear algebra optimized with the SuiteSparse JIT compiler to target dense and sparse kernels for CPUs and GPUs.

One of the biggest advantages Postgres has over lots of other DBMSs out there is the fact that it allows external improvements or new features, without requiring any interactions with the core codebase, via extensions. There are many extensions each with a unique purpose(I have also written two trivial extensions pg_wal_ext and pg_table_bloat )
