api.moorages
Description
The moorages table stores locations where vessels can stay (marinas, anchorages, etc.). Each moorage has geographic coordinates and metadata.

Constraints
| Name | Type | Definition | Comment |
|---|---|---|---|
| moorages_geog_consistent | CHECK | CHECK ((geog = geography(st_makepoint(longitude, latitude)))) | Ensure geog column is consistent with longitude and latitude columns |
| moorages_id_not_null | n | NOT NULL id | |
| moorages_pkey | PRIMARY KEY | PRIMARY KEY (id) | |
| moorages_stay_code_fkey | FOREIGN KEY | FOREIGN KEY (stay_code) REFERENCES api.stays_at(stay_code) ON DELETE RESTRICT | |
| moorages_updated_at_not_null | n | NOT NULL updated_at | |
| moorages_vessel_id_fkey | FOREIGN KEY | FOREIGN KEY (vessel_id) REFERENCES api.metadata(vessel_id) ON DELETE RESTRICT | Link api.stays with api.metadata via vessel_id using FOREIGN KEY and REFERENCES |
| moorages_vessel_id_not_null | n | NOT NULL vessel_id |
Indexes
| Name | Definition | Comment |
|---|---|---|
| moorages_pkey | CREATE UNIQUE INDEX moorages_pkey ON api.moorages USING btree (id) | |
| moorages_stay_code_idx | CREATE INDEX moorages_stay_code_idx ON api.moorages USING btree (stay_code) | Optimizes: Join with stays_at reference table Query pattern: JOIN stays_at ON moorages.stay_code = stays_at.stay_code Key strategy: stay_code first (join condition), vessel_id for RLS Partial index: Valid moorages with coordinates only Size: ~20 bytes per entry Used by: Moorage views joining stay type descriptions Performance: Enables efficient hash joins with stays_at lookup table |
| moorages_vessel_id_idx | CREATE INDEX moorages_vessel_id_idx ON api.moorages USING btree (vessel_id) | |
| moorages_vessel_idx | CREATE INDEX moorages_vessel_idx ON api.moorages USING btree (vessel_id, id) INCLUDE (name, stay_code, notes, home_flag, geog, latitude, longitude, user_data) WHERE (geog IS NOT NULL) | Optimizes: Vessel-specific moorage list and lookups Query pattern: SELECT * FROM moorages WHERE vessel_id=X Key strategy: vessel_id (RLS) + id (unique lookup) INCLUDE clause: All display columns for index-only scans Partial index: Only moorages with valid geographic coordinates Size: ~200-300 bytes per entry (due to user_data JSONB) Used by: Moorage list view, map displays, moorage detail lookups Performance: Enables index-only scans for most moorage queries Note: Large INCLUDE clause but justified by query patterns (small table, ~10-100 moorages per vessel) |
| moorages_vessel_updated_at_idx | CREATE INDEX moorages_vessel_updated_at_idx ON api.moorages USING btree (vessel_id, updated_at DESC) | Supports incremental sync: WHERE vessel_id = $1 AND updated_at > $cursor |
Triggers

| moorage_update_trigger | CREATE TRIGGER moorage_update_trigger AFTER UPDATE ON api.moorages FOR EACH ROW EXECUTE FUNCTION moorage_update_trigger_fn() | Automatic update of name and stay_code on logbook and stays reference |
