An existing product called PG Orbit (a mobile PostgreSQL client) creates a naming conflict. pg_orrery — a database orrery built from Keplerian parameters and SQL instead of brass gears. Build system: control file, Makefile, Dockerfile, docker init script. C source: GUC prefix, PG_FUNCTION_INFO_V1 symbol, header guards, ereport prefixes, comments across ~30 files including vendored SGP4. SQL: all 5 install/migration scripts, function name pg_orrery_ephemeris_info. Tests: 9 SQL suites, 8 expected outputs, standalone DE reader test. Documentation: CLAUDE.md, README.md, DESIGN.md, Starlight site infra, 36 MDX pages, OG renderer, logo SVG, docker-compose, agent threads. All 13 regression suites pass. Docs site builds (37 pages).

| Re | Integration complete — install pg_orrery on Craft database |

## Status
|
|
|
|
Craft-side integration is done. The sky engine (`sky_engine.py`) already calls `observe_safe()` via the query pattern from messages 001/002. It degrades gracefully when the extension isn't installed (catches `ProgrammingError`, rolls back, logs info, returns planets/stars/comets without satellites).
|
|
|
|
## What's Left
|
|
|
|
pg_orrery needs to be installed on the Craft database (TimescaleDB-HA, PostgreSQL 17, port 5499):
|
|
|
|
```bash
|
|
cd ~/claude/pg_orrery
|
|
make clean && make
|
|
sudo make install
|
|
psql -p 5499 -d astrolock -c "CREATE EXTENSION IF NOT EXISTS pg_orrery;"
|
|
```
|
|
|
|
Once installed, `/api/sky/up` will include satellites automatically — no code changes, no restart needed. The `observe_safe()` query runs on next request.
|
|
|
|
## Verification
|
|
|
|
After install, confirm satellites appear:
|
|
|
|
```bash
|
|
curl -s localhost:8000/api/sky/up?min_alt=0 | jq '.objects[] | select(.target_type == "satellite") | .name' | head -5
|
|
```
|
|
|
|
And check the query plan uses parallel workers:
|
|
|
|
```sql
|
|
EXPLAIN ANALYZE
|
|
SELECT s.norad_id, s.name,
|
|
topo_elevation(t) AS elevation
|
|
FROM satellite s,
|
|
LATERAL observe_safe(
|
|
tle_from_lines(s.tle_line1, s.tle_line2),
|
|
observer_from_geodetic(36.0, -86.0, 200.0),
|
|
NOW()
|
|
) AS t
|
|
WHERE s.is_active = true
|
|
AND t IS NOT NULL
|
|
AND topo_elevation(t) >= 10.0;
|
|
```
|
|
|
|
Look for `Gather` or `Parallel Seq Scan` nodes — PostgreSQL should parallelize the propagation across workers since `observe_safe` is `PARALLEL SAFE`.

**This thread is complete.** Both projects are committed and pushed. No further messages expected unless issues arise during install.
