字段结构 PostgreSQL 18

pg_stat_subscription_stats

字段 / COLUMN	类型 / TYPE	说明 / DESCRIPTION
`subid`	`oid`	OID of the subscription
`subname`	`name`	Name of the subscription
`apply_error_count`	`bigint`	Number of times an error occurred while applying changes. Note that any conflict resulting in an apply error will be counted in both apply_error_count and the corresponding conflict count (e.g., confl_*).
`sync_error_count`	`bigint`	Number of times an error occurred during the initial table synchronization
`confl_insert_exists`	`bigint`	Number of times a row insertion violated a NOT DEFERRABLE unique constraint during the application of changes. See insert_exists for details about this conflict.
`confl_update_origin_differs`	`bigint`	Number of times an update was applied to a row that had been previously modified by another source during the application of changes. See update_origin_differs for details about this conflict.
`confl_update_exists`	`bigint`	Number of times that an updated row value violated a NOT DEFERRABLE unique constraint during the application of changes. See update_exists for details about this conflict.
`confl_update_missing`	`bigint`	Number of times the tuple to be updated was not found during the application of changes. See update_missing for details about this conflict.
`confl_delete_origin_differs`	`bigint`	Number of times a delete operation was applied to row that had been previously modified by another source during the application of changes. See delete_origin_differs for details about this conflict.
`confl_delete_missing`	`bigint`	Number of times the tuple to be deleted was not found during the application of changes. See delete_missing for details about this conflict.
`confl_multiple_unique_conflicts`	`bigint`	Number of times a row insertion or an updated row values violated multiple NOT DEFERRABLE unique constraints during the application of changes. See multiple_unique_conflicts for details about this conflict.
`stats_reset`	`timestamp with time zone`	Time at which these statistics were last reset

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。
