User-Level SQL Tests (2026-01-08)

Tests executed against running HeliosDB server via PostgreSQL protocol.

Feature	Tests	Passed	Failed	Status	Notes
Time Series (basic)	4	3	1	PARTIAL	CREATE/INSERT/ORDER BY pass; GROUP BY protocol issue
Window Functions	3	3	0	PASS	ROW_NUMBER, SUM OVER, RANK all working
Streaming/Batch	2	2	0	PASS	LIMIT batching, COUNT validation
SIMD Aggregations	7	7	0	PASS	COUNT, SUM, AVG, MIN, MAX all correct on 1000-row table
SIMD Filters	4	0	4	FAIL	WHERE clause predicate evaluation errors
SIMD Sorting	3	0	3	FAIL	ORDER BY returns no results
SIMD Scans	2	0	2	FAIL	Column projection returns no results
GROUP BY	1	0	1	FAIL	Protocol D message field count mismatch
PG17 MERGE Statement	1	0	1	FAIL	Security validator false positive

SIMD SQL Test Details (2026-01-08):

• Server: ./target/release/heliosdb-full --postgres-port 15434
• Test table: simd_numbers with 1000 rows (id, val1, val2, category)
• Aggregations work correctly: SUM=500500, COUNT=1000, AVG=500.5, MIN=1, MAX=1000
• WHERE predicates fail with “Column ID not found in schema”
• ORDER BY/LIMIT queries return “no results to fetch”
• LIKE expressions unsupported in current implementation

Known Issues:

• GROUP BY with aggregates returns unexpected field count in protocol “D” message
• Default password is password (not heliosdb)

Next Steps

1. Build and test with core-only (minimal) features DONE
2. Build and test with full features DONE (20/20 groups enabled)
3. Add sub-feature tests per crate DONE (22 tests, 12 passed)
4. Fix range scan with AND conditions (parser issue)
5. Implement SELECT current_user / session_user / now() without FROM
6. Fix MIN/MAX together in SELECT (returns invalid format)
7. Fix GROUP BY aggregate counting
8. Implement CREATE EXTENSION statement
9. Adjust security validator to allow special chars in strings
10. Add SQL-level tests for extended features (NL2SQL, Federation, etc.)
11. Investigate PostgreSQL/HTTP port binding issues
