Disable WAL-skipping optimization for COPY on views
COPY can skip writing WAL when loading data on a table which has been
created in the same transaction as the one loading the data, however
this cannot work on views as this would result in trying to flush
relation files which do not exist. So disable the optimization so as
commands are able to work the same way with any configuration of
wal_level.
A test is added to cover this case, which needs to have wal_level set to
minimal to allow the problem to show up, and that is not the default
configuration.
