# does not cause the schema to be reloaded and (b) does not cause any
# other problems.

#-------------------------------------------------------------------------
# The following tests work as follows:
#
#    1.0: Open connection [db1] and populate the database.
#
#    1.1: Using "PRAGMA writable_schema", destroy the database schema on
#         disk. The schema is still in memory, so it is possible to keep
#         using it, but any attempt to reload it from disk will fail.
#
#    1.3-4: Open connection db2. Check that it can see the db schema. Then
#           close db1 and check that db2 still works. This shows that closing
#           db1 did not reset the in-memory schema.
#
#    1.5-7: Similar to 1.3-4.
#
#    1.8: Close all database connections (deleting the in-memory schema).
#         Then open a new connection and check that it cannot read the db.
