Amy commented on HAWQ-1317: --------------------------- We just port part of this pg bug fix for now which is fix out-of-range characters part, about the cancel_requested part, we will port in the future. Because postgres 9.6 adds some extra functions in regex code, e.g. cancel_requested logic. And this pg bug fix includes cancel_requested code. So, need more efforts to investigate whether we should add extra functions to regex code in this commit. > Port "Fix some regex issues with out-of-range characters and large char > ranges" from pg > --------------------------------------------------------------------------------------- > > Key: HAWQ-1317 > URL: https://issues.apache.org/jira/browse/HAWQ-1317 > Project: Apache HAWQ > Issue Type: Bug > Components: Security > Affects Versions: 2.1.0.0-incubating > Reporter: Amy > Assignee: Amy > Fix For: 2.2.0.0-incubating > > > After review of hawq code base and [CentOS 6 postgresql security > update|http://centoserrata.nagater.net/item/CESA-2016-0347-CentOS-6.Security.i386.x86_64.html], > it shows that hawq is impacted.
