4.6.0-rc1

@steadybrew/postgresjs@4.6.0-rc1 makes new connections cheaper and fixes COPY, subscribe() and TLS errors on Cloudflare Workers. No breaking changes.

npm install @steadybrew/postgresjs@4.6.0-rc1

• Opening a connection costs less CPU with SCRAM-SHA-256 passwords.
• On Cloudflare Workers, COPY ... TO STDOUT streams and sql.subscribe() work.
• On Cloudflare Workers, a server whose certificate Workers don't trust, such as Supabase's, fails at once with TLS_CLOSED.
• On Cloudflare Workers, ssl: 'prefer' connects without TLS when the server doesn't offer it.
• On Deno, sslnegotiation: 'direct' connects to PostgreSQL 18.

See the changelog for details and upstream references.

Feedback wanted before 4.6.0: connection errors or slower logins with SCRAM-SHA-256 (Node.js, Deno and Workers), and anything on Cloudflare Workers.

Validation: CI passed on Node 22/24/26 × PostgreSQL 15–18, Deno and workerd (run); Workers CPU per connection no higher than 4.5.1 (run).
