The patch v19 LGTM. - v19 applies cleanly for me - Full clean build OK - HTML docs build and render OK - The 'make check' tests all pass for me - Also cfbot reports latest patch has no errors -- http://cfbot.cputube.org/
So, I marked it a "Ready for Committer" in the CF -- https://commitfest.postgresql.org/42/4162/ ------ Kind Regards, Peter Smith. Fujitsu Australia
