It is not performance optimized yet.\n\nExisting Postgres extensions and procedural language extensions such as\nPL\u002FPython, PL\u002FPerl, and PL\u002FTcl are not generally compatible yet. Some bundled\ncontrib modules are already ported, and more compatibility may be possible over\ntime.\n\n## Roadmap\n\n- multithreaded Postgres internals\n- built-in connection pooling\n- better JSON-heavy workload support\n- fast forking and branching workflows\n- storage experiments, including no-vacuum designs\n- runtime guardrails for bad queries and AI-generated SQL\n- fewer sudden bad plan switches\n\n## Try It\n\nTry the WebAssembly demo at https:\u002F\u002Fpgrust.com.\n\nDocker:\n\n```bash\ndocker run -d --name pgrust -e POSTGRES_PASSWORD=secret malisper\u002Fpgrust:v0.1 && until docker exec -e PGPASSWORD=secret pgrust psql -h 127.0.0.1 -U postgres -c '\\q' >\u002Fdev\u002Fnull 2>&1; do sleep 1; done && docker exec -it -e PGPASSWORD=secret pgrust psql -h 127.0.0.1 -U postgres; docker rm -f pgrust\n```\n\nThis uses the `psql` client inside the Docker image.\n\n`malisper\u002Fpgrust:latest` currently points at the same release, but `v0.1` is the\npinned launch image.\n\n## Build From Source\n\nmacOS:\n\n```bash\nbrew install icu4c openssl@3 libpq\n\nexport LIBRARY_PATH=\"$(brew --prefix openssl@3)\u002Flib:${LIBRARY_PATH:-}\"\nexport PKG_CONFIG_PATH=\"$(brew --prefix openssl@3)\u002Flib\u002Fpkgconfig:$(brew --prefix icu4c)\u002Flib\u002Fpkgconfig:${PKG_CONFIG_PATH:-}\"\nexport PATH=\"$(brew --prefix libpq)\u002Fbin:$PATH\"\n```\n\nDebian\u002FUbuntu:\n\n```bash\nsudo apt-get update\nsudo apt-get install -y build-essential pkg-config libicu-dev libssl-dev libldap2-dev libpam0g-dev postgresql-client-18\n```\n\nBuild:\n\n```bash\nPGRUST_PGSHAREDIR=\"$PWD\u002Fvendor\u002Fpostgres-18.3\u002Fshare\" \\\ncargo build --release --locked --bin postgres\n```\n\nCreate a data directory:\n\n```bash\ntarget\u002Frelease\u002Fpostgres --initdb \\\n  -D \u002Ftmp\u002Fpgrust-data \\\n  -L \"$PWD\u002Fvendor\u002Fpostgres-18.3\u002Fshare\" \\\n  --no-locale \\\n  --encoding UTF8 \\\n  -U postgres\n```\n\nRun pgrust:\n\n```bash\nulimit -s 65520\n\nRUST_MIN_STACK=33554432 target\u002Frelease\u002Fpostgres \\\n  -D \u002Ftmp\u002Fpgrust-data \\\n  -F \\\n  -c listen_addresses= \\\n  -k \u002Ftmp \\\n  -p 5432 \\\n  -c io_method=sync \\\n  -c max_stack_depth=60000\n```\n\nConnect:\n\n```bash\npsql -h \u002Ftmp -p 5432 -U postgres -d postgres \\\n  -c \"select version(), 1 + 1 as two\"\n```\n\n## Regression Tests\n\nRun the Postgres regression tests against pgrust:\n\n```bash\nPGRUST_BIN=\"$PWD\u002Ftarget\u002Frelease\u002Fpostgres\" \\\nscripts\u002Frun-regression\n```\n\nThe runner uses pgrust's own `--initdb` plus the vendored Postgres 18.3 test\nfiles in this repository.
