Hello,
(sorry my english, google translate)

When I drop tables that does not exist, the drop may remain in queue.

sql>DROP TABLE ci__data__agregats ; DROP TABLE ci__data__reporting ;DROP TABLE ci__data__reporting_ci ; DROP TABLE ci__data__reporting_regle; DROP TABLE ci__data__resultats; DROP TABLE ci__data__resultats_datamart; DROP TABLE ci__data__traductions; DROP TABLE ci__ref__calcul_final; DROP TABLE ci__ref__traductions_agregats; DROP TABLE src__arv__achat; DROP TABLE src__bil__commandes; DROP TABLE src__eve__abo; DROP TABLE src__eve__qlf; DROP TABLE src__eve__vpc; DROP TABLE src__mia__inscrits; DROP TABLE src__sdv__inscrits;

4 tuples (1.504ms)

We do a lot of drop followed by create table.
We believe that this is related to a concern for duplication in the catalog table (table xxx is not single, corrupt catalog?)
