Re: postgis after pg_upgrade

Hi,
But my understanding is that this approach is used when upgrading PostGIS.
I'm upgrading postgresql from 9.4 to 9.6 and PostGIS version remains the
same (2.4.5).
If I execute:
drop extension postgis;
CREATE EXTENSION postgis SCHEMA postgis;
select PostGIS_full_version();

postgis_full_version
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
POSTGIS="2.4.5 r16765" PGSQL="96" GEOS="3.6.2-CAPI-1.10.2 4d2925d6"
PROJ="Rel. 4.9.3, 15 August 2016" GDAL="GDAL 1.11.4, released 2016/01/25"
LIBXML="2.9.1" LIBJSON="0.11" RASTER

everything looks OK. Is this wrong?

Regards,
Slavcho
