Totally agree with the puzzling assortment of a rubric. PostgreSQL supports role based-access control, RBAC. Not to mention, with PostgreSQL and the pgvector extension, you have a whole list of languages ready to use it:

C++ pgvector-cpp C# pgvector-dotnet Crystal pgvector-crystal Dart pgvector-dart Elixir pgvector-elixir Go pgvector-go Haskell pgvector-haskell Java, Scala pgvector-java Julia pgvector-julia Lua pgvector-lua Node.js pgvector-node Perl pgvector-perl PHP pgvector-php Python pgvector-python R pgvector-r Ruby pgvector-ruby, Neighbor Rust pgvector-rust Swift pgvector-swift

Wonder how many of those other Vector databases play nice.
