Hi
The performance bottleneck in LWLockRelease()method goes through an array
one by one to see which lock was released with O(N). As soon as the lock is
found it performs an array to remove the lock.
As linear search and compaction delays the release of the lock forcing the
other Postgres instances WAiting for the lock to be released
Is any possible solution like
1. LWLockRelease() releases the lock first and then remove held lock from
the array
2. Binary search (like non-linear structure) to reduce on high searching
and remove all held locks
