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. !> \q -- This message was sent by Atlassian JIRA (v6.3.4#6332)
