Doc: Improve description of the "batch_size" option for postgres_fdw.
Document that the actual number of rows postgres_fdw inserts at once in
the COPY case is determined in a similar way to the INSERT case, but it
has a restriction that does not apply to the INSERT case.
Follow-up for commit 97da48246.
