 ### Added
 
+- PostgreSQL ICU collation provider in Create Database (PG 15+). Provider picker is added when the server reports PG 15 or newer. ICU locale list comes from `pg_collation`. SQL emission is version-aware: PG 16+ uses unified `LOCALE`, PG 15 uses `ICU_LOCALE` with `LC_COLLATE 'C' LC_CTYPE 'C'`.
 - Connection URL parsing: SSH `user:password@host` split, `safeModeLevel` from TablePlus URLs, case-insensitive query params
 - Connection URL export: SSH password, Redis database index, MongoDB auth params (`authSource`, `authMechanism`, `replicaSet`), and multi-host
 - SSH Private Key auth resolves keys from `~/.ssh/config` and default locations (`id_ed25519`, `id_rsa`, `id_ecdsa`) when no explicit key path is set

 ### Changed
 
+- Create Database dialog is now driver-driven. Each driver discovers its own valid options (PostgreSQL queries `pg_collation` and `pg_database`, MySQL/MariaDB query `information_schema.character_sets`/`collations`). The hardcoded macOS-flavored locale list is gone. Engines that don't support creation hide the Create button instead of failing on click.
 - Introduced TableRows, Row, and Delta value types in TablePro/Models/Query/ as the foundation for the data grid row model rewrite. No callers migrated yet (Phase C.1 of the DataGrid refactor).
 - DataChangeManager extracted a PendingChanges value type that owns cross-collection invariants for cell edits, row insertions, and deletions. DataChangeManager kept undo/redo registration, plugin SQL generation, and the `@Observable` boundary, dropping from ~960 to ~190 lines. The serialization DTO `TabPendingChanges` is renamed to `TabChangeSnapshot` to distinguish it from the live tracker.
 - AnyChangeManager uses ChangeManaging protocol instead of closure-based type erasure, removing all runtime `[Any]` downcasts

 - Connection form: `usePrivateKey=true` from URL no longer disables Test/Create buttons
 - Transient connections from URL clean up keychain entries on connection failure
 - Native Search Field focus regression when clearing text
+- PostgreSQL Create Database failed with `new collation incompatible with template database` on glibc-initialized servers (#927). Encodings, collations, and the `template1` defaults are now read from the server. `LC_CTYPE` mirrors `LC_COLLATE`, and `TEMPLATE template0` is added automatically when the chosen collation differs from `template1.datcollate`.
+- Redshift Create Database emitted PostgreSQL `LC_COLLATE` syntax which is invalid Redshift grammar. Now emits `COLLATE { CASE_SENSITIVE | CASE_INSENSITIVE }`.
