It seems that the same QueryDesc entry is reused when executing
a generic plan.
For exemple marking queryDesc->plannedstmt->queryId (outside
pg_stat_statements) with a pseudo tag during ExecutorStart
reappears in later executions with generic plans ...
Is this QueryDesc reusable by a custom plan ? If not maybe a solution
could be to add a flag in queryDesc->plannedstmt ?
(sorry, I haven't understood yet how and when this generic plan is
managed during planning)
