Hello all,
I have a system which is giving me the log hint to increase max_locks_per_transaction. This is somewhat expected due to the workload - but what I can't understand is the numbers:
Based on the docs I calculate my theoretical max locks as:
max_locks_per_transaction * (max_connections + max_prepared_transactions)
256 * (600 + 0) = 153600
However, looking at my Prometheus monitoring (polling every 15s) which does a SELECT from pg_locks and groups by mode I can see there are over 500K AccessShareLocks consistently (up to around 570K at peak).
How is this possible???
Cheers,
James Sewell,
