Add sslmode=require parameter to direct postgres connection string

[nurul3101]

Summary by CodeRabbit

• Bug Fixes
  • Enforces SSL for direct database connections by default, improving connection security.
  • Applies only when a direct host is configured; other connection paths are unchanged.
  • No changes to public APIs or configuration formats; existing setups with SSL-ready databases continue to work without adjustments.

Walkthrough

The direct PostgreSQL connection string construction in create-db/index.js now appends ?sslmode=require when a direct host is used. This modifies the directConn value and its output (directConnectionString) without changing control flow, error handling, or exported/public entity signatures.

Changes

Cohort / File(s)	Summary of Changes
Direct connection SSL enforcement create-db/index.js	Appends ?sslmode=require to the direct PostgreSQL connection string when a direct host is present; affects directConn and resulting directConnectionString. No changes to exported/public signatures.

365-367: Solid default: enforce TLS on direct connection strings

Appending ?sslmode=require for the direct connection is a sensible baseline. It aligns with best practices (avoids accidental plaintext connections) and keeps the change tightly scoped with no control-flow impact. LGTM.

365-367: Quick compatibility sweep

• Verified that Node pg (node-postgres) parses and honors ?sslmode=require in a connection URI (it enables TLS without certificate verification by mapping to ssl.rejectUnauthorized = false) (node-postgres.com, scaleway.com).
• No other occurrences of ssl= or sslmode= were found in the repo except at create-db/index.js:366, so there’s no duplicate or conflicting guidance.
• All README snippets under create-db, create-postgres, and create-pg consistently use the postgresql:// prefix (Node pg also supports postgres://, so either works) (npmjs.com).
• If consumers require full server-certificate verification, they can pass a driver-specific SSL config object (e.g.

  new Client({
    connectionString: 'postgresql://…?sslmode=require',
    ssl: { rejectUnauthorized: true, ca: fs.readFileSync('root.crt') },
  })

  ) rather than relying solely on the URI parameter.

Not a blocker—this string will work for Node pg users.
