pg_stat_progress_cluster

Whenever CLUSTER or VACUUM FULL is running, the pg_stat_progress_cluster view will contain a row for each backend that is currently running either command. The tables below describe the information that will be reported and provide information about how to interpret it.

字段结构 PostgreSQL 18

pg_stat_progress_cluster

字段 / COLUMN	类型 / TYPE	说明 / DESCRIPTION
`pid`	`integer`	Process ID of backend.
`datid`	`oid`	OID of the database to which this backend is connected.
`datname`	`name`	Name of the database to which this backend is connected.
`relid`	`oid`	OID of the table being clustered.
`command`	`text`	The command that is running. Either CLUSTER or VACUUM FULL.
`phase`	`text`	Current processing phase. See Table 27.41.
`cluster_index_relid`	`oid`	If the table is being scanned using an index, this is the OID of the index being used; otherwise, it is zero.
`heap_tuples_scanned`	`bigint`	Number of heap tuples scanned. This counter only advances when the phase is seq scanning heap, index scanning heap or writing new heap.
`heap_tuples_written`	`bigint`	Number of heap tuples written. This counter only advances when the phase is seq scanning heap, index scanning heap or writing new heap.
`heap_blks_total`	`bigint`	Total number of heap blocks in the table. This number is reported as of the beginning of seq scanning heap.
`heap_blks_scanned`	`bigint`	Number of heap blocks scanned. This counter only advances when the phase is seq scanning heap.
`index_rebuild_count`	`bigint`	Number of indexes rebuilt. This counter only advances when the phase is rebuilding index.

标记“隐式列”的字段不包含在 SELECT * 中；部分早期统计视图由同版本源码补全，额外来源会显示在字段说明中。
