Hello!
max_locks_per_transaction enforces some restriction: the_locks_count <=
the_threshold
the_threshold is max_locks_per_transaction * (max_connections +
max_prepared_transactions), the documentation is quite clear.
What is the_locks_count?
In docs we see "no more than this many distinct objects can be locked at
any one time".
What kinds of locks should we include? does the limit really restricts
*distinct* objects count and what is the distinction key for every lock
kind?
What should one change in the following query to make it show the value
limited by the_threshold?
select count(distinct relation) + count(distinct (classid, objid)) from
pg_locks
