Hi hackers,

For local invalidation messages, there is no need to call

`InvalidateCatalogSnapshot` to set the CatalogSnapshot to NULL and
 rebuild it later. Instead, just update the CatalogSnapshot's `curcid`
 in `SnapshotSetCommandId`, this way can make the CatalogSnapshot work
well too.
 This optimization can reduce the overhead of rebuilding CatalogSnapshot
 after each command.

 

Best regards, xiaoran
