------------------------------------
Summary: Add a policy that can prevent SQL statements from running
if they contain certain functions / operators
Key: CALCITE-5292
URL: https://issues.apache.org/jira/browse/CALCITE-5292
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Add a policy that can prevent SQL statements from running if they contain
certain operators, including built-in functions and operators.
One use of this policy would be to disable functions that contain serious bugs.
For example, we could have prevented use of {{EXTRACTVALUE}} as a workaround to
CALCITE-5263.
Calcite's predecessor [LucidDB|https://github.com/LucidDB/luciddb] had
policy-driven access to tables, but this code was never fully enabled in
Calcite. Ironically, the last remaining code was deprecated in CALCITE-4953. We
should consider reviving the policy and making it handle tables and
functions/operators.
