pg_stat_progress_copy

Whenever COPY is running, the pg_stat_progress_copy view will contain one row for each backend that is currently running a COPY command. The table below describes the information that will be reported and provides information about how to interpret it.

字段结构 PostgreSQL 18

pg_stat_progress_copy

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 on which the COPY command is executed. It is set to 0 if copying from a SELECT query.
`command`	`text`	The command that is running: COPY FROM, or COPY TO.
`type`	`text`	The I/O type that the data is read from or written to: FILE, PROGRAM, PIPE (for COPY FROM STDIN and COPY TO STDOUT), or CALLBACK (used for example during the initial table synchronization in logical replication).
`bytes_processed`	`bigint`	Number of bytes already processed by COPY command.
`bytes_total`	`bigint`	Size of source file for COPY FROM command in bytes. It is set to 0 if not available.
`tuples_processed`	`bigint`	Number of tuples already processed by COPY command.
`tuples_excluded`	`bigint`	Number of tuples not processed because they were excluded by the WHERE clause of the COPY command.
`tuples_skipped`	`bigint`	Number of tuples skipped because they contain malformed data. This counter only advances when a value other than stop is specified to the ON_ERROR option.

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。
