## 📋 What's Included in v0.2.6

### Critical Fixes
1. ✅ **E0283 Type Inference Error** - Fixed in `functions.rs:96`
2. ✅ **E0515 Borrow Checker Violation** - Fixed in `executor.rs:30`
3. ✅ **Missing SQL Definitions** - Added all 12 SPARQL/RDF functions (88 lines)
4. ✅ **82 Compiler Warnings** - Eliminated (100% clean build)

### SPARQL/RDF Functions Added
All 12 W3C SPARQL 1.1 functions now registered and working:

| Function | Purpose |
|----------|---------|
| `ruvector_create_rdf_store()` | Create RDF triple stores |
| `ruvector_sparql()` | Execute SPARQL queries with format selection |
| `ruvector_sparql_json()` | Execute SPARQL and return JSONB |
| `ruvector_insert_triple()` | Insert RDF triples |
| `ruvector_insert_triple_graph()` | Insert into named graphs |
| `ruvector_load_ntriples()` | Bulk load N-Triples format |
| `ruvector_rdf_stats()` | Get store statistics |
| `ruvector_query_triples()` | Query by pattern (wildcards) |
| `ruvector_clear_rdf_store()` | Clear all triples |
| `ruvector_delete_rdf_store()` | Delete stores |
| `ruvector_list_rdf_stores()` | List all stores |
| `ruvector_sparql_update()` | Execute SPARQL UPDATE |

### Quality Metrics
- **Compilation Errors**: 0 (was 2)
- **Compiler Warnings**: 0 (was 82)
- **Build Time**: ~2 minutes
- **Docker Image**: 442MB (optimized)

## 🚀 How to Use

### Pull Docker Image
```bash
# Latest version
docker pull ruvnet/ruvector-postgres:latest

# Specific version
docker pull ruvnet/ruvector-postgres:0.2.6
```

### Use in Rust Project
```toml
[dependencies]
ruvector-postgres = "0.2.6"
```

### Run PostgreSQL with SPARQL
```bash
docker run -d \
  --name ruvector-db \
  -e POSTGRES_USER=ruvector \
  -e POSTGRES_PASSWORD=ruvector \
  -e POSTGRES_DB=ruvector_test \
  -p 5432:5432 \
  ruvnet/ruvector-postgres:0.2.6

# Create extension
psql -U ruvector -d ruvector_test -c "CREATE EXTENSION ruvector CASCADE;"

# Create RDF store
psql -U ruvector -d ruvector_test -c "SELECT ruvector_create_rdf_store('demo');"

# Execute SPARQL query
psql -U ruvector -d ruvector_test -c "
  SELECT ruvector_sparql('demo',
    'SELECT ?s ?p ?o WHERE { ?s ?p ?o }',
    'json'
  );
"
```

## 📝 Commit History

```
00c8a67f - chore(postgres-cli): Bump version to 0.2.6
53451e39 - fix(postgres): Achieve 100% clean build - resolve all compilation errors and warnings
bd3fcf62 - docs(postgres): Add SPARQL/RDF documentation to README files
```

## ✅ Verification

To verify the installation:

```sql
-- Check extension version
SELECT extversion FROM pg_extension WHERE extname = 'ruvector';
-- Result: 0.2.5 (extension version from control file)

-- Check available SPARQL functions
SELECT count(*) FROM pg_proc
WHERE proname LIKE '%rdf%' OR proname LIKE '%sparql%' OR proname LIKE '%triple%';
-- Result: 12

-- List all ruvector functions
\df ruvector_*
-- Result: 77 functions total
```

## 🎯 Next Steps

1. **Test SPARQL queries** in your application
2. **Load your RDF data** using `ruvector_load_ntriples()`
3. **Execute queries** using `ruvector_sparql()`
4. **Monitor performance** with `ruvector_rdf_stats()`
5. **Report issues** at https://github.com/ruvnet/ruvector/issues
