* fix: pin postgres image to bookworm in docker_example to prevent collation mismatch The postgres:16 tag silently moved its base from Debian Bookworm (glibc 2.36) to Trixie (glibc 2.41), causing a recurring collation version mismatch warning on existing langflow-postgres volumes. Pin to postgres:16-bookworm in both docker-compose files and update the README so existing data volumes keep matching the OS locale data. Refs: https://github.com/langflow-ai/langflow/issues/9608 * docs: pin postgres image to bookworm in current docs compose snippets Mirror the docker_example pin in the four current docs that publish copyable Compose snippets pairing postgres:16 with a persistent langflow-postgres volume. Prevents the same Bookworm-to-Trixie collation version mismatch warning when users follow docs instead of docker_example. Versioned historical docs are left as-is. Refs: https://github.com/langflow-ai/langflow/issues/9608 * fix: switch postgres pin from bookworm to trixie for OS consistency Aligns the pinned postgres base with the langflow runtime image, which moved to Debian Trixie in #12990. Keeping postgres on bookworm would have diverged the stack and locked the database to an aging glibc that will receive fewer security backports as bookworm ages into oldstable. The pin itself still solves the original bug — postgres:16 cannot silently roll its OS underneath an existing volume. Document the one-time REFRESH COLLATION VERSION step for users upgrading from a bookworm-initialized volume in docker_example/README.md. Refs: https://github.com/langflow-ai/langflow/issues/9608
