Ming LI created HAWQ-1068:
-----------------------------
Summary: master process panic with signal 11 when call
get_ao_compression_ratio(null)
Key: HAWQ-1068
URL: https://issues.apache.org/jira/browse/HAWQ-1068
Project: Apache HAWQ
Issue Type: Bug
Components: Catalog
Reporter: Ming LI
Assignee: Lei Chang
Fix For: backlog
Customer has a function which will call get_ao_compression_ratio() to pass the
relation name dynamically. However in some corner case
get_ao_compression_ratio() will be passed with NULL, which triggered a signal
11 and crashed the master process.
The issue could be easily reproduced in house as shown below:
gpadmin=# select get_ao_compression_ratio(null);
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
