..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

..since it needs to be restored after any child indexes are restored *and
attached*.  The order needs to be:

1) restore child and parent index (order doesn't matter);
2) attach child index;
3) set cluster on child and parent index (order doesn't matter);

Yes, I've updated the patch as suggested.

You're right. I've removed the check for proc->pid == 0.

Also I added a check for proc->fpLockBits[group] == 0 in GetLockConflicts().

The latest version of the patch is attached.

Maybe, but I'm not sure if we really need this..

Subject: [PATCH v2] Optimize iteration over PGPROC for fast-path lock
 searches.

This commit improves efficiency in FastPathTransferRelationLocks()
and GetLockConflicts(), which iterate over PGPROCs to search for
fast-path locks.

Previously, these functions recalculated the fast-path group during
every loop iteration, even though it remained constant. This update
optimizes the process by calculating the group once and reusing it
throughout the loop.

The functions also now skip empty fast-path groups, avoiding
unnecessary scans of their slots. Additionally, groups belonging to
inactive backends (with pid=0) are always empty, so checking
the group is sufficient to bypass these backends, further enhancing
performance.

Hi Fujii-san,

It seems that this was forgotten somehow.

The patch still applies.

Examining c4d5cb71d229095a39fda1121a75ee40e6069a2a, it seems that this patch
could have been part of that commit as well. But may be it wasn't so apparent
that time. I think it's a good improvement.

I like this. Moving the group computation out of the loop also allows
the computed group to be used for checking existence of lock. That's
double benefit. This test is similar to the test in
GetLockStatusData(), so we already have a precedence.

There's a comment
* proc->databaseId is set at backend startup time and never changes
* thereafter, so it might be safe to perform this test before
* acquiring &proc->fpInfoLock.

that seems to assume that databaseid is never cleared, so maybe it's
not safe to do this.

The performance gain from this patch might be tiny and may not be
visible. Still, have you tried to measure the performance improvement?

Thanks for reviewing the patch!

I’ve updated the patch as suggested. Updated patch is attached.

I haven’t measured the actual performance gain since the patch optimizes
the logic in a clear and logical way. While we might see some improvement
in artificial scenarios — like with a large max_connections and
all backends slots having their databaseIds set, I’m not sure
how meaningful that would be.

Subject: [PATCH v3] Optimize iteration over PGPROC for fast-path lock
 searches.

This commit improves efficiency in FastPathTransferRelationLocks()
and GetLockConflicts(), which iterate over PGPROCs to search for
fast-path locks.

Previously, these functions recalculated the fast-path group during
every loop iteration, even though it remained constant. This update
optimizes the process by calculating the group once and reusing it
throughout the loop.

The functions also now skip empty fast-path groups, avoiding
unnecessary scans of their slots. Additionally, groups belonging to
inactive backends (with pid=0) are always empty, so checking
the group is sufficient to bypass these backends, further enhancing
performance.

Fair enough. The code is more readable this way. That itself is an improvement.

I stared at c4d5cb71d229095a39fda1121a75ee40e6069a2a to see whether
there's any reason this was left aside at that time. I am convinced
that it was just missed. I think this patch is good to be committed.
