[postgis-users] topology : statue of topogeom composition?
Hello everybody. a question mostly for Sandro I'm afraid. What is the current status of postgis topology regarding composition between topogeometry? First of all is it possible to have topogeometry composed of other topogeometry, themselves composed of other geometry, and so one? Second, if this is possible, are this kind of topogeometry properly maintained when there is a change in the low level topology (splitting an edge for instance). I think I know the answers, but I really would like to be sure. Thanks =) Cheers, Rémi ___ postgis-users mailing list postgis-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/postgis-users
[postgis-users] document work-around for restore and materialized view issue
I guess a lot of people are being bitten by this: https://trac.osgeo.org/postgis/ticket/2485 https://lists.osgeo.org/pipermail/postgis-users/2015-November/040944.html and it's getting kinda depressing. Given that we can't come up with a solution we can all agree with, I was thinking of just documenting my general work-around fix. BTW as mentioned, this is not just an issue affecting rster. It also really bites you if you use materialized views as it tries to populate data during restore and fails. Anywaon have an issue with me - documenting the work around in a postgis.net tip section and a link to the tip in the FAQs?

Yes you can ignore. It's possible for whatever reason that wasn't marked as an exclude from backup and the data got saved but is shipped with PostGIS. I think pramsey came across that and fixed in 2.2.1. At anyrate its a harmless error if your backup is stet to ignore errors which is the default.

[postgis-users] restore problem
OK trying this again without the prior messages to avoid the max limits. Apologies if my original appears, when I tried to cancel the posting it seemed to ask for a ‘cookie’ code I did not have! Anyhow, thanks to everyone. D From: Darrel Maddy Sent: 12 November 2015 09:51 To: PostGIS Users Discussion Subject: RE: [postgis-users] restore problem Dear Regina, Many thanks again for this detailed explanation – this really does help me understand what is happening. I did not have the clean flag set BUT when I tried this again this morning it has worked ☺. I have tried this on two databases now and both seem to have restored the raster data. Clearly I would not have figured this out without your instruction! It is a shame that this process is not as easy as I am sure everyone would like it to be but the workaround is simple once you know how and as long as this is documented I don’t see this as a deal breaker. On one of my databases I do get a new (presumably trivial) error: pg_restore: processing data for table "spatial_ref_sys" pg_restore: [archiver (db)] Error while PROCESSING TOC: pg_restore: [archiver (db)] Error from TOC entry 3303; 0 35941 TABLE DATA spatial_ref_sys postgres pg_restore: [archiver (db)] COPY failed for table "spatial_ref_sys": ERROR: duplicate key value violates unique constraint "spatial_ref_sys_pkey" DETAIL: Key (srid)=(5013) already exists. This only happened on the second database I tried to restore and it may not be a significant issue. Should I ignore this? Many thanks again from a very relieved Darrel ___ postgis-users mailing list postgis-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/postgis-users
