Attached is an attempt at an explanation of the edge cases I was

The return value of _bt_bottomupdel_pass() is advisory; it reports
"failure" for a deletion pass that was just suboptimal (it rarely
reports failure because it couldn't delete anything at all). Bottom-up
deletion preemptively falls back on a version-orientated deduplication
pass when it didn't

Your request is essentially to wrap the GMP library into native types in
Postgres. This can be done as custom types and adding postgres extensions as
you suggested originally. The work to be done is straightforward, but there is
a lot of work so it would take a awhile to implement. The big

Given the number of posts you’ve made I would have to conclude that the
answer to that question is no.

Dear PostgreSQL Hackers,
I have been trying to get a reply or interest in either updating
PostgreSQL to support High Precision mathematical types,
with arithmetic and elementary functions support, or release
of an Extension which has accomplished the same thing.
Is there someone on this email

A side table has the nice additional benefit that we can very easily
version the *table structure* so when we ALTER TABLE and the table
structure changes we just make a new side table with now-currents
structure.
Also we may want different set of indexes on historic table(s) for
whatever reason

. Allow extended statistics on column expressions;
. Memoize node which can improve speed of nested loop joins;
. Allow use of LZ4

That's not entirely true. [1] says
When writing an interval constant with a fields specification, or when
assigning a string to an interval column
