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 or foreign table 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. Tests are added to cover the different cases, which need to have wal_level set to minimal to allow the problem to show up, and that is not the default configuration. Reported-by: Luis M.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
