Support Extended Query

[trietphm]

Do you have any plan to support the Extended Query?

I can try implementing it but I don't know the detailed specs to start with.

Hi 👋, I recently started to work on the extended query protocol.

The jackc/pgx driver uses the extended query protocol and is included within the tests. Feel free to uncomment the test case and check it out.

I have just pushed my changes to a feature branch (feat/extended-queries). Feel free to check it out and open a discussion / issue if you would like to work on something.

I am planning to make this feature compatible with the simple query handler allowing to handle complex queries with just a single handler. Extended query handlers and components could be overridden through options. I have made an draft for this feature within the feature branch.

@trietphm I have just opened a draft PR to include support for extended queries. Feel free to take a look.

Great! I definitely will check it soon and give feedback if needed.
