We've had a system in operation for a few years that makes use of a substantial amount of partitioning. The parent table now has over 4,000 children tables. Within the last couple of days the server started giving "out of shared memory" errors with the suggestion to increase the max_locks_per_transaction.
If the parent table is queried will it require a lock for each one of the child tables? I'm guessing it will.
