Pull Request Overview

This PR introduces a feature to abort requests when they timeout and updates the Postgres connection method by replacing the pg Pool with the postgres package.

• Aborts server requests on timeout by triggering the abort flag on the request context.
• Replaces the pg connection logic with the postgres library and updates the query execution and cancellation logic using RxJS.

• Using 'sql.unsafe' may expose the application to SQL injection risks; ensure that 'msg.req.query' is properly sanitized or otherwise deemed safe for unsafe execution.

const query = sql.unsafe(msg.req.query);

[nitpick] Consider adding an inline comment to clarify that triggering the abort flag intentionally stops further processing on timeout; this will improve code readability and maintainability.

Suggested change

	console.info(formatTime(Date.now()), `ServerError`, JSON.stringify(message), err);
	console.info(formatTime(Date.now()), `ServerError`, JSON.stringify(message), err);
	// Intentionally trigger the abort flag to stop further processing on timeout

pg lib 中的 Pool 不具备 cancel 能力：

• how is the way for cancel query? brianc/node-postgres#773
• Pool cancel query brianc/node-postgres#2261
• Cancellable Query with AbortSignal option brianc/node-postgres#3212
• query cancel brianc/node-postgres#1392

因此改用 postgres-js 替代
