If the same extension is in two different paths mentioned in extension_control_path,
it is impossible to install the version of the last one.
postgres=# show extension_control_path ;
extension_control_path
-----------------------------------------------------------------------------
$system:/extensions/meilleureextension/share:/extensions/monextension/share
(1 row)
postgres=# select * from pg_available_extensions where name like '%mon%';
name | default_version | installed_version | comment
--------------+-----------------+-------------------+---------------
monextension | 2.0 | | Meilleure
monextension | 1.0 | | Mon extension
(2 rows)
postgres=# create extension monextension version "1.0" ;
ERROR: extension "monextension" has no installation script nor update path for version "1.0"
postgres=# create extension monextension ;
CREATE EXTENSION
postgres=# select * from pg_available_extensions where name like '%mon%'; name | default_version | installed_version | comment
--------------+-----------------+-------------------+--------------- monextension | 2.0 | 2.0 | Meilleure monextension | 1.0 | 2.0 | Mon extension
Don't you think that the command
create extension monextension version "1.0" ;
should be accepted by checking in all paths ?
