[postgis-users] restore problem

Tue Nov 10 13:51:50 PST 2015

Hi Tim,

Yes, when I create the extension in an empty database  st_bandmetadata(raster,integer) is listed as a function in the public schema.

Hi Tim,

I am on windows and using the latest version 2.2 of postgis (and postgresql 9.4). My original databases do not have pg_raster as an extension – I am assuming that is not required now?

I think it is anyway lumped in with postgis, but it certainly seems that the raster based functions are missing:

pg_restore: [archiver (db)] COPY failed for table "dems": ERROR:  function st_bandmetadata(public.raster, integer[]) does not exist
LINE 1:  SELECT array_agg(pixeltype)::text[] FROM st_bandmetadata($1

If you create an empty db, ensure that postgis extension is enabled can you check that it has st_bandmetadata present before doing the restore?

My cheat of loading postgis before doing the restore is a simpler workaround for Bborie’s process since the st_* functions from your backup (with their possibly incorrect lib paths) will be rejected if the functions are already installed, but the rest of the data in your dump *should* restore.

Dear Tim,

Thanks for this suggestion.  I had assumed that the extensions were part of the backup as they appear on the manifest and indeed they appear in the restored database.

Alas this made no difference – I just tried it, creating the extension first before restore and I get exactly the same error.

And is pg_raster also installed in the target db before doing the restore? I don’t know if it is considered best practice by the postgis guru’s, but I usually install any extensions before doing a restore to deal with version differences between source and target systems gracefully...

Regards

Tim

Dear all,

Like many here I suspect I want to keep a copy of my main databases held on my workstation, on my laptop. I used PgAdmin to backup the databases concerned (the backup files look about the size I was expecting)  but restore on my laptop did not successfully complete.  All my shp file tables restored without issues but my raster tables (these are tiled rasters) would not. Looking at the error in the restore window of PgAdmin this appears to be a problem with a function/constraint.

pg_restore: processing data for table "dems"
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 3459; 0 94054 TABLE DATA dems postgres

LINE 1:  SELECT array_agg(pixeltype)::text[] FROM st_bandmetadata($1...
                                                  ^

I did a quick search and found some old chatter on this issue but from the messages I read I would have expected this issue to have been cleared up in postgis 2 .

Obviously I cannot contemplate having mission critical data in a database which does not backup/restore correctly so I am assuming there is a fix which avoids this issue or there is another way to make a copy of the database for transfer elsewhere?

Have you enabled the PostGIS extension on the destination database before attempting to restore?

Regards

Tim

Once again any help would be gratefully received.

Best wishes

Darrel

ps.   Apologies for the string of questions I have asked lately – I will go silent once more shortly as I must move on to other things.
