I understand the need to reduce open file handles, despite the
possibilities enabled by using large numbers of small file sizes.
Snowflake, for instance, sees everything in 1MB chunks, which makes
massively parallel sequential scans (Snowflake's _only_ query plan)
possible, though I don't know if they accomplish that via separate files,
or via segments within a large file.

I am curious whether a move like this to create a generational change in
file file format shouldn't be more ambitious, perhaps altering the block
format to insert a block format version number, whether that be at every
block, or every megabyte, or some other interval, and whether we store it
in-file or in a separate file to accompany the first non-segmented. Having
such versioning information would allow blocks of different formats to
co-exist in the same table, which could be critical to future changes such
as 64 bit XIDs, etc.
