Hi, Ted!
The two asserts out of four could be combined as you proposed in the patch.
Assert added by 941aa6a6268a6a66f6 to index_parallelscan_initialize
should remain anyway as otherwise, we can have Segfault in
SerializeSnapshot called from this function.
Assert in index_parallelscan_estimate can be omitted as there is the
same assert inside EstimateSnapshotSpace called from this function.
I've included it into version 2 of a patch.
Not sure it's worth the effort but IMO the patch is right and can be committed.
Kind regards,
Pavel Borisov,
Supabase.
