[jira] [Commented] (HAWQ-1317) Port "Fix some regex issues with
out-of-range characters and large char ranges" from pg
[ https://issues.apache.org/jira/browse/HAWQ-1317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15858897#comment-15858897 ]
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.
