Onder Kalaci 04fcd73eb6 When reaches to shared pool size, COPY sets the placement access 
It looks like we forgot to set the placement accesses, and
this could lead to self-deadlocks on complex transaction blocks.

fix NaN cost estimate on empty columnar tables (#4593) 
Fixing a division by zero in the cost calculations for scanning a columnar table.

Due to how the columns in a columnar table are counted an empty table would result in a division by zero. Instead this patch keeps the column selection ratio on zero when this happens, resulting in an accurate cost of zero pages to scan a columnar table.

fix parse error on pg11.8 for extension creation (#4582) 
In pg11.8 it seemingly tries to parse the full sql file creating the extension,
since we use syntax introduced in postgres 12 this fails.

This patch rewrites the statement not recognized by pg11.8 to be dynamically
executed from a string literal via `EXECUTE`.

Mitigate segfault in connection statemachine (#4551) 
As described in the comment, we have observed crashes in production
due to a segfault caused by the dereference of a NULL pointer in our
connection statemachine.

As a mitigation, preventing system crashes, we provide an error with
a small explanation of the issue. Unfortunately the case is not
reliably reproduced yet, hence the inability to add tests.

DESCRIPTION: Prevent segfaults when SAVEPOINT handling cannot recover from connection failures

Choose the smallest colocation id among all matches (#4559) 
Currently we choose an arbitrary colocation id from all the matches for
a colocation id. This could mean that 2 distributed tables, which have
the same scheme could go into different colocation groups. This fix
makes sure that the same match will go to the same colocation group.
