In the Remote Operations line, the FDW/extension could print any info about remote operations, eg, "Scan/Join + Aggregate".
"Foreign" implies this node is processed by FDW, but "Procesing" gives us no extra information; seems to me redundant.
I intentionally chose that word and thought we could leave detailed descriptions about remote operations to the FDW/extension; a broader word like "Processing" seems to work well because we allow various kinds of operations to the remote side, in addition to scans/joins, to be performed in that one Foreign Scan node indicated by "Foreign Processing", such as aggregation, window functions, distinct, order by, row locking, table modification, or combinations of them.
"Scan" is a better word than "Processing". From plan's perspective it's ultimately a Scan (on the data produced by the foreign server) and not processing.
