| * Object ID (OID) zero is InvalidOid. |
| * |
| * OIDs 1-9999 are reserved for manual assignment (see the files |
| * in src/include/catalog/). |
| * |
| * OIDS 10000-16383 are reserved for assignment during initdb |
| * using the OID generator. (We start the generator at 10000.) |
| * |
| * OIDs beginning at 16384 are assigned from the OID generator |
| * during normal multiuser operation. (We force the generator up to |
| * 16384 as soon as we are in normal operation.) |
| * |
| * The choices of 10000 and 16384 are completely arbitrary, and can be moved |
| * if we run low on OIDs in either category. Changing the macros below |
| * should be sufficient to do this. |
| * |
| * NOTE: if the OID generator wraps around, we skip over OIDs 0-16383 |
| * and resume with 16384. This minimizes the odds of OID conflict, by not |
| * reassigning OIDs that might have been assigned during initdb. |
