Hi,

In postgresAcquireSampleRowsFunc, we 1) determine the fetch size and
then 2) construct the fetch command in each iteration of fetching some
rows from the remote, but that would be totally redundant.  Attached
is a patch for removing that redundancy.

I'll add this to the upcoming commitfest.

Best regards,
Etsuro Fujita
