Description

> CREATE TABLE TEST_5 (ID INTEGER NOT NULL PRIMARY KEY, HOST VARCHAR(10), FLAG BOOLEAN);

> CREATE VIEW TEST_5_VIEW (col1 INTEGER, col2 INTEGER, col3 INTEGER, col4 INTEGER, col5 INTEGER) AS SELECT * FROM TEST_5 WHERE ID>10;

> CREATE INDEX TEST_5_INDEX ON TEST_5_VIEW(COL4);

> DROP TABLE test_5 CASCASE;

Table, view, and index are dropped, but in the sandbox' log I see:

Note that this only happens in the sandbox, so it's not important to fix.
