default_storage_engine was introduced in MySQL 5.5.3.
storage_engine was removed in MySQL 5.7.5.

`action="."` strips query parameters from the URL which is not usually what

If SQLITE_MAX_VARIABLE_NUMBER (default = 999) is changed at compile time
to be greater than SQLITE_MAX_COLUMN (default = 2000), which Debian does

containing more than 2000 parameters when DEBUG = True.
