Hello, this is ... nth version of the patch.

> Thank you. Everything seems clear.
> Please wait for a while.

libpq-fe.h
- PQskipResult() is added instead of PGskipRemainigResults().

fe-exec.c
- PQskipResult() is added instead of PGskipRemainigResults().
- PQgetRowProcessor() is added.

dblink.c
- Use PQskipReslt() to skip remaining rows.
- Shorten the path from catching exception to rethrowing it. And
  storeInfo.edata has been removed due to that.
- dblink_fetch() now catches exceptions properly.

libpq.sgml
- PQskipResult() is added instead of PGskipRemainigResults().
- Some misspelling has been corrected.

regards,
