Summary

• Add PostgreSQL transaction-pooler support with pooled application connections and a direct connection variant for schema and maintenance workflows.
• Enable emulated prepares for pooled PostgreSQL connections while keeping direct connections on native prepares by default.
• Add ::direct routing for the database manager, migrations, schema dump/load, and maintenance commands.
• Preserve explicit ::read, ::write, --read, --write, and --pooled routing, and make php artisan db default to direct only when pooled mode is enabled.
• Handle boolean bindings correctly when PostgreSQL uses PDO-side emulated prepares.

Benefit to end users

Many PostgreSQL providers, including Neon and PlanetScale through PgBouncer and AWS RDS Proxy, use transaction-mode pooling. Today, Laravel users must handle prepared statement behavior, boolean binding edge cases, and direct DDL routing themselves. This gives Laravel applications a framework-level path for using PostgreSQL connection proxying and pooling without custom connection wrappers.

Backward compatibility

• Default PostgreSQL connections without pooled => true or a configured direct endpoint keep the existing native-prepare behavior.
• Existing read/write connection suffixes and CLI flags remain explicit and are not rerouted to direct.
• php artisan db only defaults to direct when pooled mode is enabled and a direct endpoint exists, so adding a direct endpoint alone does not change the default interactive CLI target.
• Boolean binding behavior is unchanged for native prepares and only adjusts PostgreSQL emulated prepares to send true / false strings instead of integer literals.
• PGSSLMODE is only exported for schema dump/load when an sslmode value is configured.
