Hi, To my understanding, a select on a table does acquire an access share lock on that table. my question is: is there any other kind of lock that a select may acquire ? obviously, all explicit locking schemes like select for update, etc... is out of this question scope.
I was wondering if for example, within a join, some kind of lock may be acquired so that the dataset concerned is not changed during execution ? (for example a delete then autovacuum ??) thanks Marc MILLAS Senior Architect +33607850334 www.mokadb.com
