Another thing: if realloc() fails, the old pointer stays valid.
So it needs to be assigned to temp variable first, before
overwriting old pointer.
And seems malloc() is preferable to palloc() to avoid
exceptions inside row processor. Although latter
one could be made to work, it might be unnecessary
complexity. (store current pqresult into remoteConn?)
