# This block tests that if one client modifies the database schema, a |
# second client updates its internal cache of the database schema before |
# executing any queries. Specifically, it does not return a "no such column" |
# or "no such table" error if the table or column in question does exist |
# but was added after the second client loaded its cache of the database |
# schema. |
# |
# Types of schema modifications: |
# |
# 1. Adding a database table. |
# 2. Adding a database view. |
# 3. Adding a database index. |
# 4. Adding a database trigger. |
# 5. Adding a column to an existing table (ALTER TABLE). |
