Type OIDs
NodeDB maps its types to PostgreSQL OIDs for pgwire compatibility.
| NodeDB Type | PostgreSQL Type | OID |
| STRING | text | 25 |
| INT | int8 | 20 |
| FLOAT | float8 | 701 |
| BOOL | bool | 16 |
| TIMESTAMP | timestamptz | 1184 |
| UUID | uuid | 2950 |
| DECIMAL | numeric | 1700 |
| ARRAY | jsonb | 3802 |
| OBJECT | jsonb | 3802 |
| GEOMETRY | bytea | 17 |
Complex types (ARRAY, OBJECT) are serialized as JSONB over pgwire. GEOMETRY is serialized as WKB (bytea).
