Greetings,
Note that it lists RASTER both as being unpackaged and needing an upgrade, even though postgis_raster is apparently not installed. My thinking is that somewhere along the way, postgis_raster and possibly topology were installed and later uninstalled (perhaps after being unbundled?).
I recently took over the management of a postgresql + postgis db on aws rds. Given the age of this project, the db itself is probably ~7-8 years old. It is currently on v12.12 and I'm unable to upgrade it to 13+. The db does use postgis, but as far as I can tell, no raster or topology or other postgis-related fields/features.
When I try to upgrade on aws, I get the following error:
The instance could not be upgraded because there are one or more databases with an older version of PostGIS extension or its dependent extensions (address_standardizer, address_standardizer_data_us, postgis_tiger_geocoder, postgis_topology, postgis_raster) installed.
Please upgrade all installations of PostGIS and drop its dependent extensions and try again.
SELECT postgis_full_version(); gives the following (reformatted for clarity):
POSTGIS="3.1.7 aafe1ff" [EXTENSION]
PGSQL="120"
GEOS="3.8.2-CAPI-1.13.4"
PROJ="Rel. 5.2.0, September 15th, 2018"
GDAL="GDAL 2.4.4, released 2020/01/08"
LIBXML="2.9.1"
LIBJSON="0.13.1"
LIBPROTOBUF="1.3.2"
WAGYU="0.5.0 (Internal)"
RASTER (raster lib from "2.5.5 r0" need upgrade) [UNPACKAGED!] (raster procs from "2.5.2 r17328" need upgrade)
For more clues, I issued the following command. For clarity I replace the account numbers with pseudo-usernames for clarity. Also note that schema_1 and schema_2 are two schemas that the project uses.
db=> select a.extname, a.extowner, a.extnamespace, a.extversion, b.nspname, b.nspowner from pg_catalog.pg_extension a, pg_namespace b where a.extname LIKE '%postgis%';

I'm not familiar enough with postgresql nor postgis to understand whether the nspname entries for tiger, topology, etc. are expected, or offer clues as to the problem that I am encountering.
Some things that I've tried:
db=> SELECT postgis_extensions_upgrade();
NOTICE: Extension postgis_raster is not available or not packagable for some reason
NOTICE: Extension postgis_topology is not available or not packagable for some reason
NOTICE: Extension postgis_tiger_geocoder is not available or not packagable for some reason
postgis_extensions_upgrade
-------------------------------------------------------------------
Upgrade completed, run SELECT postgis_full_version(); for details
Also:
db=> select * from pg_available_extensions where name like 'postgis%';

postgis | 3.1.7 | 3.1.7 | PostGIS geometry and geography spatial types and functions
postgis_tiger_geocoder | 3.1.7 | | PostGIS tiger geocoder and reverse geocoder
postgis_topology | 3.1.7 | | PostGIS topology spatial types and functions
postgis_raster | 3.1.7 | | PostGIS raster types and functions(4 rows)
And:
db=> \dx

postgis | 3.1.7 | extensions | PostGIS geometry, geography, and raster spatial types and functions
sslinfo | 1.2 | public | information about SSL certificates

And:
db=> CREATE EXTENSION postgis_raster;
ERROR: PostGIS Raster is already installed in schema 'extensions'
CONTEXT: PL/pgSQL function inline_code_block line 10 at RAISE
And:
db=> DROP EXTENSION postgis_raster;
ERROR: extension "postgis_raster" does not exist
I also did a snapshot backup and restored to a new instance on aws, and this resulted in exactly the same problem on the new instance.
So I'm both stuck and confused. It seems that I'm in the middle of a partial upgrade/install that broke along the way. Does anyone have other suggestions on what I might try? I'd like to get to v13+ with only postgis (no raster, topology, etc.) installed without losing any data along the journey. Is my only recourse to do a full data backup to sql followed by creating a new instance and restoring data?
Thanks,
->jvp
