[DOC] Fix for the missing pg_stat_progress_cluster view phase column value
Hi,
I found a missing column value in the pg_stat_progress_cluster view document.
I read the src/backend/catalog/system_views.sql file, there seems to be a possibility that 'writing new heap' is output in the 'phase' column.
The attached patch adds a description of the 'writing new heap' value output in the 'phase' column.
Regards,
Noriyoshi Shinoda

Good catch!
By the way the table mentions the phases common to CLUSTER and VACUUM FULL. I wonder why some of them are described as "CLUSTER is" and others are "The command is"..
regards.

Because VACUUM FULL does not use the sort-and-scan mode, no?

Thank you for your response.

The 'writing new heap' phase seems to appear only when the CLUSTER statement is executed. When I read the table_relation_copy_for_cluster function, it seems to be a phase that is executed only during sorting.
