Package: postgis
Version: 2.3.1+dfsg-2
Severity: normal
Tags: upstream

Dear Maintainer,

Version 2.3.1 of postgis has a bug whereby geometry queries can sometimes fail.
For example:

mapit=# create table test (geo geometry);
CREATE TABLE
mapit=# insert into test values 
mapit-# ('0101000020E61000007D91D0967329E4BF6631B1F9B8D64A40'::geometry), 
mapit-# ('0101000020E6100000E2AFC91AF510C1BFCDCCCCCCCCAC4A40'::geometry);
INSERT 0 2
mapit=# create index on test using gist (geo);
CREATE INDEX
mapit=# vacuum analyze test;
VACUUM
mapit=# set enable_seqscan = false;
SET
mapit=# select * from test ORDER BY geo::geometry <->
mapit-# ('0101000020E610000092054CE0D6DDE5BFCDCCCCCCCCAC4A40'::geometry);
ERROR:  index returned tuples in wrong order
mapit=# drop table test;
DROP TABLE
mapit=# 

This was reported upstream at: https://trac.osgeo.org/postgis/ticket/3418
And fixed in postgis 2.3.2, the 2.3 commit fixing it is here:
https://trac.osgeo.org/postgis/changeset/15285

Is there any chance this could be included/backported to fix the issue
in stretch?

ATB,
Matthew

The severity of this issue needs to be important or higher to be
eligible for a stable update. The upstream issue is classified as
medium, which doesn't seem severe enough to increase the severity of
this bugreport to important unfortunately.

I suggest you cherry-pick the upstream commit and include it as a patch
in an unofficial update of the stretch package to host in your own apt
repository.

Kind Regards,

Bas
