I do not feel it applies to my case. I tried to create a partitioned 
table that inherits columns from a base table. The documentation you 
provided the URL seems to speak of realising partitioning by using 
inheritance.

This needs a code example to go any further.

Sorry, my bad. I posted the URL of the table that is inherited from. The 
recepient is 
https://sourceforge.net/p/treintaytres/code/HEAD/tree/trunk/code_files/data_storage/PostgreSQL/tables/TOPO_FILES.pg_sqlcreate 
table if not exists TOPO_FILES (

     SOURCE_ID          uuid
        constraint TOPO_FILES␟FK_01
            references SOURCES (ID)
            match full
        not null
    ,FILE_NAME          text
        not null
    ,TILE               raster
        not null
    ,FILE_CREATION_PIT  timestamp(6) with time zone
        not null
    ,FILE_HASH          text
        not null
    ,constraint TOPO_FILES␟PK primary key (ID)
    ,constraint TOPO_FILES␟UQ unique (SOURCE_ID
                                     ,FILE_NAME)
)
inherits(TEMPLATE_TECH);
-- partition by hash (source_id); --NOTE Up to PG 17, partitioning with 
inheriting table is not possible.


The spender table 
ishttps://sourceforge.net/p/treintaytres/code/HEAD/tree/trunk/code_files/data_storage/PostgreSQL/tables/TEMPLATE_TECH.pg_sql

create table if not exists TEMPLATE_TECH (
     ID                 uuid
        constraint TEMPLATE_TECH␟PK primary key
        not null
        default gen_random_uuid()
    ,ENTRY_PIT          timestamp(6) with time zone
        not null
        default clock_timestamp()
);
