pg_grpc – Call gRPC services directly from PostgreSQL

What it does

pg_grpc turns any gRPC service into a first-class SQL function call. No codegen, no middleware, no app-layer glue. Invoke RPCs from triggers, materialized views, scheduled jobs, or ad-hoc queries. # Install (see https://csenshi.github.io/pg_grpc/installation for all paths) cargo pgrx install --release --no-default-features --features pg18 CREATE EXTENSION pg_grpc; SELECT grpc_call( ' grpcb.in:9001 ' , ' grpcbin.GRPCBin/DummyUnary ' , ' {"f_string": "hello"} ' ::jsonb, options => ' {"tls": {}} ' ::jsonb ); Documentation 📚 csenshi.github.io/pg_grpc - installation, TLS, user-supplied protos, recipes, fullfrom github.com

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
