Can't repackage postgis_raster with postgis_extensions_upgrade when postgis not installed in public

[robe]

CREATE SCHEMA postgis;
ALTER DATABASE test SET search_path=public, contrib, postgis, tiger, utility;

-- reconnect

CREATE EXTENSION postgis SCHEMA postgis VERSION "2.5.3";

-- disconnect

-- reconnect

SELECT postgis_full_version(); --is at 2.5.3

SELECT postgis_extensions_upgrade();

-- outputs

POSTGIS="3.0.0 r17983" [EXTENSION] PGSQL="110" GEOS="3.8.0-CAPI-1.13.1 " PROJ="Rel. 5.2.0, September 15th, 2018" GDAL="GDAL 2.4.2, released 2019/06/28" LIBXML="2.9.9" LIBJSON="0.12" LIBPROTOBUF="1.2.1" WAGYU="0.4.3 (Internal)" RASTER (raster lib from "2.5.3 r17699" need upgrade) [UNPACKAGED!] (raster procs from "2.5.3 r17699" need upgrade)

Repeat again

SELECT postgis_extensions_upgrade();

Gives error:

To force repackaging I had to do this:

CREATE EXTENSION postgis_raster FROM unpackaged VERSION "3.0.0" SCHEMA postgis;

I thought I had tested this already, but I've always been doing

ALTER EXTENSION postgis UPDATE;

So perhaps this only happens if you don't do ALTER EXTENSION postgis UPDATE because the 2.5.3 is incomplet.

Looks like this is a duplicate of #4581 so closing this one out
