[postgis-users] Failed to upgrade PostGIS Raster from 2.2.5 to 3.0 on RDS

[Regina Obe]

This looks like  an issue specific to PostGIS on Amazon.  

The only work arounds I can think of such as first upgrading the PostGIS raster with the script approach would not work on Amazon because of the security restrictions they have put in place.

 

I think this is something they need to fix on their end.

 

Thanks,

Regina

Subject: [postgis-users] Failed to upgrade PostGIS Raster from 2.2.5 to 3.0 on RDS

 

Hi,

 

We are currently using PostgreSQL 9.6.11 / PostGIS 2.3.7 on RDS.

 

Because AWS started to support pg12/PostGIS3.0 recently, we are trying to upgrade our PostGIS database to 3.0.

 

Then, I am facing a problem that could not upgrade postgis_raster to 3.0.0. I need some help if possible.

 

My upgrading procedures are as follows.

 

1. I upgrade postgis from 2.2.5 to 2.3.7 on the current RDS database by following SQL.

ALTER EXTENSION postgis UPDATE;

 

2. I upgrade PostgreSQL from 9.6.11 to 9.6.17 by AWS management console

 

3. Then, I upgrade PostGIS from 2.3.7 to 2.5.2 by using following SQL.

ALTER EXTENSION postgis UPDATE TO '2.5.2';
WARNING:  'postgis.gdal_datapath' is already set and cannot be changed until you reconnect
WARNING:  'postgis.gdal_enabled_drivers' is already set and cannot be changed until you reconnect
WARNING:  'postgis.enable_outdb_rasters' is already set and cannot be changed until you reconnect

There are some warnings appeared, but I think it's not problems...I continued.

 

4. I upgraded PostgreSQL from 9.6.17 to 12.2 by AWS management console

 

5. I upgraded PostGIS from 2.5.2 to 3.0.0 by following SQL.

 

ALTER EXTENSION postgis UPDATE TO '3.0.0';
WARNING:  unpackaging raster
WARNING:  PostGIS Raster functionality has been unpackaged
HINT:  type `SELECT postgis_extensions_upgrade(); to finish the upgrade. After upgrading, if you want to drop raster, run: DROP EXTENSION postgis_raster;
ALTER EXTENSION

Then, I tried as follow;

SELECT postgis_extensions_upgrade();
 
NOTICE:  Packaging extension postgis_raster
WARNING:  'postgis.gdal_datapath' is already set and cannot be changed until you reconnect
WARNING:  'postgis.gdal_enabled_drivers' is already set and cannot be changed until you reconnect

ERROR:  cannot create temporary table within security-restricted operation
CONTEXT:  SQL statement "CREATE EXTENSION postgis_raster FROM unpackaged"
PL/pgSQL function postgis_extensions_upgrade() line 48 at EXECUTE

After running "SELECT postgis_extensions_upgrade();", its error appeared and I could not upgrade postgis_raster from 2.5.2 to 3.0.0. 

 

Current PostGIS version is like below. 

SELECT postgis_full_version();
postgis_full_version                                                                                                                                                                   
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(1 row)

 

Although most of our databases do not use raster functions, a database is using raster functions. I found upgraded databases on PostGIS3.0 is working very well apart from a database which is using postgis_raster.

 

I tried to search the solution on how to upgrade postgis_raster, but I could not find any information about it. It is maybe some particular problem of RDS, I don't know...

 

I found a information on AWS Developer Forum, someone faced the same error..but there is no solution on the site.

https://forums.aws.amazon.com/thread.jspa?messageID=938665

 

Does anyone have a similar experience of this error? If so, I want to get some advice on how to solve it..

 

Best Regards,

Jin Igarashi
