This pipeline is used to specify the SQL tables not to be imported during the restore of an internal SPIP backup.
It is called by the lister_tables_noimport function in the ecrire/base/dump.php file. It accepts as parameter and returns as output an array containing the list of database tables not to be imported:
$IMPORT_tables_noimport = pipeline('lister_tables_noimport', $IMPORT_tables_noimport);
