Getting all entries in a single block with ctid

[Tore Halvorsen <tore.halvorsen@xxxxxxxxx>]

Hi,

As I understand it, the ctid contains both the block number and an index is this block.
Is there a way to fetch all the table entries from the same block?

E.g. something like this:

select * from foo where ctid like '(123,%'

or ... ctid.block = 123
