When postgres_fdw begins an asynchronous data fetch, it submits FETCH query by using PQsendQuery(). If PQsendQuery() fails and returns 0, postgres_fdw should report an error. But, previously, postgres_fdw reported an error only when the return value is less than 0, though PQsendQuery() never return the values other than 0 and 1. Therefore postgres_fdw could not handle the failure to send FETCH query in an asynchronous data fetch. This commit fixes postgres_fdw so that it reports an error when PQsendQuery() returns 0. Back-patch to v14 where asynchronous execution was supported in postgres_fdw.
