Subject: BUG #17229: Segmentation Fault after upgrading to version 13
Date: Wed, 13 Oct 2021 17:57:05 +0000
Message-ID: <17229-bc836b4d1d2633bf@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 17229
Logged by: Efrain Berdecia
Email address: ejberdecia@yahoo.com
PostgreSQL version: 13.1
Operating system: Linux 3.10.0-1160.11.1
Description:
Ever since we upgraded to PostgreSQL version 13 we are sporadically getting
segmentation faults for the following process and all existing connections
get killed and our streaming replication process goes down. The sql below
does establish a dblink to a Greenplum cluster. For reference, this is our
log_line_prefix value;
