feat: PostgreSQL Tracing Support

[kamilogorek]

PostgreSQL and CockroachDB tracing support.

Usage:

constSentry=require("@sentry/node");constTracing=require("@sentry/tracing");constpg=require("pg");Sentry.init({dsn: "__PUBLIC_DSN__",integrations: [newTracing.Integrations.Postgres(),],tracesSampleRate: 1.0,});constclient=newpg.Client({user: "postgres",password: "docker",});client.connect();// the rest of the code, for raw-node code we need manual instrumentation, eg.consttransaction=Sentry.startTransaction({op: "transaction",name: "My Transaction",});Sentry.configureScope((scope)=>{scope.setSpan(transaction);});client.query("SELECT $1::text as message",["Hello world!"],(err,res)=>{console.log(err ? err.stack : res.rows[0].message);// Hello World!if(transaction)transaction.finish();client.end();});

Works nicely with Express too:

constSentry=require("@sentry/node");constTracing=require("@sentry/tracing");constpg=require("pg");constexpress=require("express");Sentry.init({dsn: "__PUBLIC_DSN__",integrations: [newSentry.Integrations.Http({tracing: true}),newTracing.Integrations.Express({app: express.Router,methods: ["get"],}),newTracing.Integrations.Postgres(),],});constapp=express();constclient=newpg.Client({user: "postgres",password: "docker",});client.connect();app.use(Sentry.Handlers.requestHandler());app.use(Sentry.Handlers.tracingHandler());app.use(express.json());app.get("/hi",functionsayHi(req,res){client.query("SELECT $1::text as name",["picklerick"],(err,rows)=>{res.send(rows[0]);});});app.use(Sentry.Handlers.errorHandler());app.listen(3000);

Thanks @lobsterkatie, will make appropriate changes once I finish Mongo work.

Is there a timeline for when this will be merged and released? The Express fix in here would be really nice to have given it is causing a lot of duplicates in our issues page.

@dlaudate-embark I'll extract it from the PR today so we can ship it tomorrow/monday

Looks good! Maybe some tests, though?
