I've updated pgsql_fdw so that it can collect statistics from foreign
data with new FDW API.
Other changes from latest version are:
- Now pgsql_fdw uses libpq row processor API to get rid of SQL-level cursor.
- Introduced new struct ErrorPos to integrate error reporting in foreign
scan and analyze.
- Some refactoring, such as removing unnecessary parameter.
- Fix typos.
