# Version matrix

> The reconciled PostgreSQL 13–18 wait-event inventory, including renames and type moves.
---

The matrix reconciles two factual paths: PostgreSQL 13–16 monitoring tables and live `pg_wait_events` rows from PostgreSQL 17–18 Docker instances.

| Version | Extraction authority | Rows |
| --- | --- | ---: |
| 13 | Official monitoring documentation | 222 |
| 14 | Official monitoring documentation | 231 |
| 15 | Official monitoring documentation | 238 |
| 16 | Official monitoring documentation | 246 |
| 17 | Docker `postgres:17`, queried from `pg_wait_events` | 265 |
| 18 | Docker `postgres:18`, queried from `pg_wait_events` | 274 |

The union contains **327 exact `(type, name)` identities**. Forty-five historical identities resolve into **282 semantic dossiers**: 281 core event entries plus one Extension mechanism placeholder. The mappings cover two type moves in PG14, two reviewed Parallel Hash renames in PG16, and PostgreSQL's PG17 wait-name spelling normalization.

The CSV deliberately preserves old and new names as separate rows and provides a `canonical` column. Event pages consolidate those rows through explicit aliases without erasing their real version ranges.

## Rename policy {#rename-policy}

Names are linked only when the evidence is deterministic: the adjacent replacement is alphanumerically identical after case normalization, or the source/documentation establishes the reviewed rename. Similar descriptions alone are not enough; removals such as `PgStatMain` remain historical events rather than speculative aliases.
