Actually in the code base the style of that variable declaration and usage of pgstat_progress_update_multi_param is a mix. For instance, in lazy_scan_heap, ReindexRelationConcurrently, the variables are declared at the start of the function. And in _bt_spools_heapscan, index_build, validate_index, perform_base_backup, the variables are declared within a separate block. IMO, we can have the arrays declared at the start of the functions i.e. the way it's done in v8-0001, because we can extend them for reporting some other parameter(maybe in future). > >> - I fir the "io_target" name misleading, because in some cases it's > >> actually the *source*. > > > > Yes, I was also not quite happy with this, but couldn't find a better > > one at the point of writing the initial patchset.

For COPY TO the name "source_type" column and for COPY FROM the name "destination_type" makes sense. To have a combined column name for both, how about naming that column as "io_type"?
