Removes enterprise/DBA features and replaces the marginal AI bar with a
central chat agent that has progressive-discovery tools, cross-session
memory, saved-query reuse, and inline result actions. Adds ClickHouse
support alongside PostgreSQL/Greenplum.
Cleanup
- Drop ~10k LOC of advanced features: Docker, Snapshots, Validation,
Index Advisor, Role/User Management, Data Generator, ERD, Lookup.
- Trim deps: drop @xyflow/react, dagre, @types/dagre; cut tokio features
to rt-multi-thread/sync/time/net/macros.
- Remove unused TuskError variants and dead helpers (topological_sort,
invalidate_schema_cache).
Multi-DB (PostgreSQL + ClickHouse)
- New src-tauri/src/db/ module: ChClient (HTTP-based, reuses reqwest),
sql_guard (cross-flavor read-only whitelist with 8 tests).
- ConnectionConfig gains db_flavor and secure fields with serde defaults
for backwards-compatible connections.json.
- All connection/query/schema/data commands dispatch by flavor; CH
covers connect, execute_query, list_databases/schemas/tables/views/
columns/completion_schema, paginated table fetch.
- Frontend: dbCapabilities matrix, ConnectionDialog engine selector
with port auto-swap and HTTPS toggle, SqlEditor switches to
StandardSQL dialect for CH, TableDataView surfaces CH connections as
read-only.
AI-first chat agent
- New src/components/chat/ panel with composer, message rendering,
collapsible tool-call/result blocks, top-level ErrorBoundary.
- Backend agent loop in commands/chat.rs with strict-JSON tool
protocol. Nine tools: list_databases, list_tables, get_columns,
switch_database, run_query, remember, save_query, find_queries, final.
Forgiving parser accepts both flat and nested-input shapes.
- Compressed history: only the last 4 run_query results carry sample
rows (≤10, cells truncated to 200 chars) into LLM context; older
results marked omitted.
- System prompt uses lite OVERVIEW (DB list + active-DB tables only)
instead of full DDL — schema details are loaded on demand via
get_columns. CH OVERVIEW shows cross-DB tables since CH allows
db.table queries.
Cross-session memory (F1)
- Per-connection markdown file at app_data_dir/memory/<connection_id>.md,
16KB cap with oldest-block eviction. Agent appends via remember()
tool; the file is injected into LEARNED NOTES section of every system
prompt.
- New Memory sidebar tab with editable textarea, badge for note count,
empty-state with template. Edits picked up on the next agent turn.
Saved-query reuse (F2)
- Tools save_query and find_queries scoped to current connection.
save_query attaches a UUID + timestamp; find_queries returns top 10
matches with SQL preview ≤500 chars.
- Storage shared with the sidebar Saved panel.
Inline result actions (F3)
- run_query result block in chat gets Open-full (90vw × 80vh modal with
full ResultsTable, no row cap) and Export (reuses ExportDialog for
CSV/JSON via existing exportCsv/exportJson commands).
Verification
- cargo check clean, zero warnings.
- cargo test --lib: 50 pass (20 chat parser + 4 memory + 8 sql_guard +
6 clean_sql + 12 escape_ident).
- npx tsc --noEmit clean.
- npx vitest run: 20 pass.
Reformat Rust code with rustfmt, suppress clippy::too_many_arguments
for Tauri IPC commands, derive Default for AppSettings, fix unused
variable pattern in TableDataView, and add unit tests for utils.
Four new killer features leveraging AI (Ollama) and PostgreSQL internals:
- Data Validation: describe quality rules in natural language, AI generates
SQL to find violations, run with pass/fail results and sample violations
- Test Data Generator: right-click table to generate realistic FK-aware test
data with AI, preview before inserting in a transaction
- Index Advisor: analyze pg_stat tables + AI recommendations for CREATE/DROP
INDEX with one-click apply
- Data Snapshots: export selected tables to JSON (FK-ordered), restore from
file with optional truncate in a transaction

- Add AppSettingsSheet (gear icon in Toolbar) with MCP, Docker, and AI sections
- MCP Server: toggle on/off, port config, status badge, endpoint URL with copy
- Docker: local/remote daemon selector with remote URL input
- AI: moved Ollama settings into the unified sheet
- MCP status probes actual TCP port for reliable running detection
- Docker commands respect configurable docker host (-H flag) for remote daemons
- MCP server supports graceful shutdown via tokio watch channel
- Settings persisted to app_settings.json alongside existing config files
- StatusBar shows MCP indicator (green/gray dot) with tooltip

Clone any database to a local Docker PostgreSQL container with schema
and/or data transfer via pg_dump. Supports three modes: schema only,
full clone, and sample data. Includes container lifecycle management
(start/stop/remove) in the Admin panel, progress tracking with
collapsible process log, and automatic connection creation.

Enables searching for a specific column value (e.g. carrier_id=123) across all databases on a PostgreSQL server. The backend creates temporary connection pools per database (semaphore-limited to 5), queries information_schema for matching columns, and executes read-only SELECTs with real-time progress events. Results are grouped by database/table in a new "Entity Lookup" tab.

- Column sort by header click in table view (ASC/DESC/none cycle, server-side)
- SQL formatter with Format button and Shift+Alt+F keybinding (sql-formatter)
- Table size and row count display in schema tree via pg_class
- Insert row dialog with column type hints and auto-skip for identity columns
- Saved queries (bookmarks) with CRUD backend, sidebar panel, and save dialog
- Active sessions monitor (pg_stat_activity) with auto-refresh, cancel & terminate

Add Admin sidebar tab with database/role management panels, role manager
workspace tab, and privilege dialogs. Backend provides 10 new Tauri
commands for CRUD on databases, roles, and privileges with read-only
mode enforcement. Context menus on schema tree nodes allow dropping
databases and viewing/granting table privileges.

Add four developer/QA features:
- Connection color coding: color picker in dialog, colored indicators across toolbar, tabs, status bar, and connection selectors
- Query history: Rust backend with JSON file storage (500 entry cap), sidebar panel with search/clear, auto-recording from workspace
- Schema-aware SQL autocomplete: backend fetches column metadata, CodeMirror receives schema namespace with public tables unprefixed
- EXPLAIN ANALYZE visualizer: recursive tree view with cost-colored bars, expand/collapse nodes, buffers info, Results/Explain tab toggle

Add Rust backend: AppState with connection pool management,
TuskError handling, ConnectionConfig model, and all commands
for connections, schema browsing, query execution, data CRUD,
and CSV/JSON export via sqlx.
