[postgis-users] Stuck with upgrade from postgresql 9.6 to postgresql 14 due to postgis2.3

[atanga MARCELIUS]

Hello Sandro, Thanks for your support.

 Please here are the out put to the queries you suggested.

I have also attached the output in text document in a clearer format.

My main concern here is how to  manage the upgrade path from postgis 2.3 in postgresql 9.6  to  a compactible version of postgis  in postgresql14  given that postgis 2.3 was hard install(using source code) and given my environmental challenges I do not want to do a dump and restore?

1.
postgres=# SELECT postgis_full_version();                                                                            postgis_full_version                                                                            ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- POSTGIS="2.3.7 r16523" PGSQL="100" GEOS="3.9.2-CAPI-1.14.3" 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(1 row)

The above message means that database "xxxxx" does not contain
the "postgis extension". This does not necessarely mean it doesn't
contain postgis objects, if you're coming from a very old install
as you seem to be coming from.

What does this query return?

  SELECT postgis_full_version();

And this one ?

  SELECT oid::regprocedure,probin
  FROM pg_catalog.pg_proc
  WHERE proname LIKE 'postgis_%version';
