STATISTICS VIEW · 统计视图

pg_stat_autovacuum_scores

The pg_stat_autovacuum_scores view will contain one row for each table in the current database (including TOAST tables), showing the current autovacuum scores for that specific table. Autovacuum prioritizes tables deemed eligible for processing based on their score, with higher scores indicating higher priority. See Section 24.1.6.1 for more information. While this view generates its results the same way that autovacuum workers do, it does so using the current source information, which might differ from the source information that an autovacuum worker sees when it gathers its list of tables to process. Therefore, this view is not a completely reliable indicator of which tables autovacuum will process and what order it will process them.

字段结构 PostgreSQL 19

pg_stat_autovacuum_scores

字段 / COLUMN	类型 / TYPE	说明 / DESCRIPTION
`relid`	`oid`	Oid of the table.
`schemaname`	`name`	Name of the schema that the table is in.
`relname`	`name`	Name of the table.
`score`	`double precision`	Maximum value of all component scores. This is the value that autovacuum would use to sort the list of tables to process.
`xid_score`	`double precision`	Transaction ID age component score. Scores greater than autovacuum_freeze_score_weight indicate that autovacuum would vacuum the table for transaction ID wraparound prevention.
`mxid_score`	`double precision`	Multixact ID age component score. Scores greater than autovacuum_multixact_freeze_score_weight indicate that autovacuum would vacuum the table for multixact ID wraparound prevention.
`vacuum_score`	`double precision`	Vacuum component score. Scores greater than autovacuum_vacuum_score_weight indicate that autovacuum would vacuum the table (unless autovacuum is disabled).
`vacuum_insert_score`	`double precision`	Vacuum insert component score. Scores greater than autovacuum_vacuum_insert_score_weight indicate that autovacuum would vacuum the table (unless autovacuum is disabled).
`analyze_score`	`double precision`	Analyze component score. Scores greater than autovacuum_analyze_score_weight indicate that autovacuum would analyze the table (unless autovacuum is disabled).
`do_vacuum`	`boolean`文档原写法：`bool`	Whether autovacuum would vacuum the table. Note that even if the component scores indicate that autovacuum would vacuum the table, this may be false if autovacuum is disabled.
`do_analyze`	`boolean`文档原写法：`bool`	Whether autovacuum would analyze the table. Note that even if the component scores indicate that autovacuum would analyze the table, this may be false if autovacuum is disabled.
`for_wraparound`	`boolean`文档原写法：`bool`	Whether autovacuum would vacuum the table for wraparound prevention.

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。
