Question 1

How to build a PostgreSQL honeypot with PSQL Wire in Go?

Accepted Answer

Use PSQL Wire to create a server that logs or inspects incoming connections. Implement a handler to capture queries without executing them, and integrate session attributes for tracking, as shown in the examples directory.

Question 2

PSQL Wire vs pgx for PostgreSQL protocol in Go?

Accepted Answer

PSQL Wire is for building servers that speak the PostgreSQL protocol, while pgx is a client library for connecting to PostgreSQL servers. Use PSQL Wire if you need to create a custom server; use pgx for client-side interactions.

Question 3

Does PSQL Wire support prepared statements?

Accepted Answer

Yes, it provides a high-level API for prepared statements, allowing you to define custom logic for statement execution, as demonstrated in the handler example in the README.

Question 4

Can I use PSQL Wire for a production database server?

Accepted Answer

Only if you build the entire SQL engine, storage, and reliability features yourself. It's best for prototyping, testing, or specialized use cases like honeypots, not as a full database replacement.

Question 5

How to parse SQL queries with PSQL Wire?

Accepted Answer

You must integrate an external SQL parser, such as auxten/postgresql-parser mentioned in the README. PSQL Wire only handles the wire protocol, not query parsing or execution.

Question 6

What PostgreSQL wire protocol features are missing in PSQL Wire?

Accepted Answer

The README doesn't specify, but as a custom implementation, it may not support all advanced protocol extensions or error handling. Check the GitHub issues or test with your specific use case.
