pg_rewind: Fix busted sanity check.

robertmhaas · robertmhaas · commit 063ff9210c54 · 2017-07-21T12:59:22.000-04:00
As written, the code would only fail the sanity check if none of the columns returned by the server were of the expected type, but we want it to fail if even one column is not of the expected type. Discussion: http://postgr.es/m/CA+TgmoYuY5zW7JEs+1hSS1D=V5K8h1SQuESrq=bMNeo0B71Sfw@mail.gmail.com
