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);

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);

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);

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);

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);

* Simplify if/else logic of walsender CreateReplicationSlot

Hi,
While reviewing another patch I was looking at the walsender's static
function CreateReplicationSlot
I found that the current logic seemed to have some unnecessary if/else
checking which can be simplified.
~~
To summarise:
CURRENT
if (cmd->kind == REPLICATION_KIND_PHYSICAL)
{
...
}
else
{
...
}
if (cmd->kind == REPLICATION_KIND_LOGICAL)
{
...
}
else if (cmd->kind == REPLICATION_KIND_PHYSICAL && reserve_wal)
{
...
}
SUGGESTION
if (cmd->kind == REPLICATION_KIND_PHYSICAL)
{
...
if (reserve_wal)
{
...
}
}
else /* REPLICATION_KIND_LOGICAL */
{
...
}
~~~
PSA a small patch for making this change.
(I ran make check-world after this change and it was successful)
======
Kind Regards,
Peter Smith.
