When importing a database using a previous dump, The following errors appear in the error log. The sequence of three lines seem to appear once per table created. I can find no helpful reference to any of the statements.
The tables are created ok, and populated with data. I have tried this multiple times, with multiple databases, also a single table manually - in each case the result is the same:
