Hello hackers,
In his blog post (What's new in SQL 2016)[
https://modern-sql.com/blog/2017-06/whats-new-in-sql-2016], Markus Winand
explained some of the changes added to SQL:2016. I spotted that Postgres
was behind other RDBMS on hyperbolic functions and log10 function.
The log10 function existed

I like having a hard limit on the number of loop iterations;
that should ensure that the test terminates

No objection to the feature, but

I see that opossum's owner just resurrected it after a period of being
MIA ... and it's failing a few regression tests with symptoms like
this:
SELECT 'NaN'::float4;
- float4
-
-NaN
+ float4
+--
+ Infinity
(1 row)
I have no doubt that this is caused by the same platform

I understand it's not fully supported to replicate to a differently
partitioned setup on a subscriber with either pglogical or the native
logical replication, however I also know that INSERT triggers can be fired
in replication mode. I have an insert-only OLTP table that I want
partitioned only on

I assume you already considered and rejected having a fixed size null
bitmap followed by a variable size array of datums. That seems like it
would be denser and work better with cpu cache.
I guess the reason you prefer the struct is because it can be used
elsewhere on its own?
