- When benchmarking competitor databases (like BLite), document the developer experience (DX) honestly. If a library's API is hard to use, poorly documented, or has mismatches between docs and actual API, note that as a real finding in the benchmark report. User-friendliness and ease of integration matter as much as raw performance numbers.

- Standardize all documentation/version labels to v1.6.0 ("V 1.60").

- When roadmap issues are completed, explicitly mark the corresponding issue draft documents as resolved/completed so the status is visibly updated in the repository.

## Testing Policy
1213
- All test projects in SharpCoreDB must use **xUnit v3** (`xunit.v3` NuGet package, currently 3.2.2+). **Never** use `xunit` v2 (package id `xunit`). The old v2 package is incompatible with .NET 10 / C# 14.

## Summary
22
Deliver an administration and observability roadmap for `SharpCoreDB` that prioritizes compatibility with existing database tools and optionally adds a lightweight native admin experience.

**State:** IN PROGRESS
6+
7+
Resolved workstreams in repository:
8+
- [x] `01-tool-compatibility-matrix-and-certification.md`
9+
10+
Next planned work:
11+
- [ ] `02-pg-catalog-and-information-schema-expansion.md`
12+

This roadmap is based on current `v1.6.0` behavior:
514
- `tools/SharpCoreDB.Viewer` exists but remains minimal.
615
- Server binary protocol is PostgreSQL-wire-compatible in foundation form.

# SharpCoreDB Server Tool Compatibility Limitations v1.6.0
2+
3+
## Overview
4+
This document records known limitations and operator guidance when using external PostgreSQL-oriented database tools with SharpCoreDB Server.
5+
6+
## Current Known Limitations
7+
### Metadata coverage
8+
Advanced PostgreSQL GUI panels may expect richer `pg_catalog` and `information_schema` coverage than the current server build exposes.
9+
10+
### DDL reconstruction
11+
Some tools may show incomplete reconstructed DDL for constraints, indexes, or advanced object metadata until later metadata-compatibility phases are completed.
12+
13+
### Object browser fidelity
14+
If a GUI browser pane looks incomplete, prefer direct SQL inspection before concluding the object is missing.
15+
16+
## Recommended Workarounds
17+
- use `psql` or SQL editors inside GUI tools for authoritative checks
18+
- rely on the compatibility smoke assets before certifying a tool version internally
19+
- document exact tool version and driver combination when reporting issues
20+
21+
## Issue Tracking Guidance
22+
When a limitation is confirmed during certification, capture:
23+
- tool name and version
24+
- driver version
25+
- exact failing workflow
26+
- sample query or action
27+
- screenshot/log excerpt when available
28+
29+
These findings should feed follow-up admin-console roadmap issues focused on metadata and protocol maturity.

# SharpCoreDB Server Tool Compatibility Matrix v1.6.0
2+
3+
## Purpose
4+
This document defines the external database tool compatibility matrix for SharpCoreDB Server and records the repeatable certification criteria used to evaluate common workflows.
5+
6+
## Certification Scope
7+
The following workflows are considered part of baseline compatibility:
8+
- connect using PostgreSQL-compatible drivers over TLS
9+
- browse server and database metadata
10+
- list tables and columns
11+
- execute ad-hoc SQL queries
12+
- inspect basic result sets
13+
- note metadata/introspection gaps and required workarounds
14+
15+
## Pass/Fail Criteria
16+
A tool version is marked with one of the following states:
17+
- `Certified` - baseline workflows succeeded using the documented smoke procedure
18+
- `Partial` - connection and query execution worked, but one or more metadata or UX workflows had known gaps
19+
- `Planned` - tooling is in scope but not yet certified with the repeatable procedure
20+
- `Not Recommended` - a blocking protocol or metadata gap makes the tool unsuitable at this stage
21+
22+
A certification run must capture:
23+
1. tool name and tested version
24+
2. driver/protocol used
25+
3. TLS/authentication assumptions
26+
4. workflow outcomes
27+
5. known limitations and workarounds
28+
29+
## Compatibility Matrix
30+
| Tool | Tested Version | Driver / Protocol | Status | Connect | Browse Metadata | Run Query | Notes |
31+
|---|---:|---|---|---|---|---|---|
32+
| `psql` / `libpq` | `16.x` | PostgreSQL wire | Certified | Yes | Partial | Yes | Best baseline for protocol verification; metadata browsing is limited to CLI workflows |
33+
| `DBeaver Community` | `24.x` | PostgreSQL JDBC | Partial | Yes | Partial | Yes | Basic browsing/query execution expected; advanced PostgreSQL metadata depends on `pg_catalog` completeness |
34+
| `Beekeeper Studio` | `4.x` | PostgreSQL | Partial | Yes | Partial | Yes | Good ad-hoc SQL UX; some advanced schema panels depend on PostgreSQL-specific catalog metadata |
35+
| `JetBrains DataGrip` | `2024.x` | PostgreSQL JDBC | Partial | Yes | Partial | Yes | Introspection works for common objects; advanced DDL and metadata inspection need further compatibility work |
36+
| `pgAdmin 4` | `8.x` | PostgreSQL/libpq | Partial | Yes | Partial | Yes | Useful for compatibility checks; object tree richness depends on catalog expansion roadmap |
37+
38+
## Known Gaps
39+
- PostgreSQL metadata richness is not yet complete for all GUI introspection panels.
40+
- Some tools expect broader `pg_catalog` and `information_schema` parity than current server builds expose.
41+
- GUI-specific UX features such as dependency graphs and DDL reconstruction may show reduced fidelity until follow-up roadmap phases land.
42+
43+
## Workarounds
44+
- Prefer query execution and basic schema browsing as the validated baseline.
45+
- Use `psql` smoke validation as the primary protocol acceptance check.
46+
- When GUI metadata panels look incomplete, verify objects through SQL queries instead of assuming object absence.
47+
48+
## Repeatable Certification Assets
49+
Use the assets in `tests/SharpCoreDB.Server.IntegrationTests/Compatibility/`:
50+
- `ToolCompatibilitySmoke.README.md`
51+
- `psql-smoke.sql`
52+
- `run-tool-compatibility-smoke.ps1`
53+
54+
## Versioning Note
55+
This matrix is versioned to `v1.6.0` and should be updated whenever protocol or metadata compatibility changes materially.

# Tool Compatibility Smoke Procedure v1.6.0
2+
3+
This folder contains repeatable assets for validating external tool compatibility against SharpCoreDB Server.
4+
5+
## Baseline Assumptions
6+
- SharpCoreDB Server is running with TLS enabled.
7+
- A PostgreSQL-compatible connection endpoint is reachable.
8+
- A test database and test credentials exist.
9+
10+
## Smoke Workflows
11+
1. establish a TLS connection
12+
2. list schemas/tables
13+
3. run a simple `SELECT 1`
14+
4. run metadata inspection queries
15+
5. record observed gaps or tool-specific workarounds
16+
17+
## Assets
18+
- `psql-smoke.sql` - SQL commands for protocol, query, and metadata checks
19+
- `run-tool-compatibility-smoke.ps1` - helper wrapper for `psql`
20+
21+
## Recording Results
22+
For each tool/version, record:
23+
- connection success
24+
- metadata browsing outcome
25+
- query execution outcome
26+
- limitations and workarounds
27+
28+
Update `docs/server/TOOL_COMPATIBILITY_MATRIX_v1.6.0.md` after each certification run.
