No template native mode for postgresql 14+

[axellpadilla]

Just reporting back on a way to configure on not using a template table or keeping it updated for added fields, index, etc. (if you don't use non-native features on the partitioned table, just not use it), following documentation property inheritance and answer from @keithf4 on issue #556 .

First try, just create_parent() again to update the template:
Result: Function tries to create the template again (instead of replace/update it) and a duplicate relation error is shown, will this works by just changing the code to replace it, use another existing partition as a source for non-native features update?.

Second try, just drop the template table:
Result: An error is shown by run_maintenance():

ERROR: Unable to find configured template table in system catalogs: partman.template_knime_bitacora
CONTEXT: PL/pgSQL function inherit_template_properties(text,text,text) line 75 at RAISE
SQL statement "SELECT partman.inherit_template_properties(p_parent_table, v_parent_schema, v_partition_name)"

Third try, as suggested by @keithf4 on the issue #556 , use NULL on template table column of table part_config of partman.
Result: Worked perfectly, run_maintenance() created the new partitions, works also with the template table dropped. (Remember that you can't use non-native features on the partitioned tables.)

Happy to help!
