Hi All,

- Patch got applied cleanly.
- Regression make check run fine.
- Patch covered the documentation changes

Here are few comments:

1) What the need of following change:

diff --git a/src/backend/storage/lmgr/lwlock.c
b/src/backend/storage/lmgr/lwlock.c
index bcec173..9fe6855 100644
--- a/src/backend/storage/lmgr/lwlock.c

@@ -1005,12 +1005,6 @@ LWLockWaitForVar(LWLock *lock, uint64 *valptr,
uint64 oldval, uint64 *newval)

- /*

is
- * released.

- lock->releaseOK = true;
-
/* Can release the mutex now */
SpinLockRelease(&lock->mutex);

It doesn't look like related to this patch.

2)

Why above changes reqired ?

3) This patch adding IF NOT EXIST_S for CREATE TABLE AS and CREATE
MATERIALIZED
TABLE, but testcase coverage for CREATE MATERIALIZED TABLE is missing.

Apart from this changes looks good to me.
