in snapshots, per my proposal of a few days ago. Also, tweak heapam.c routines (heap_insert, heap_update, heap_delete, heap_mark4update) to be passed the command ID to use, instead of doing GetCurrentCommandID. For catalog updates they'll still get passed current command ID, but for updates generated from the main executor they'll get passed the command ID saved in the snapshot the query is using. This should fix some corner cases associated with functions and triggers that advance current command ID while an outer query is still in progress.
