Did a quick test: during review

retro=# CREATE USER josef;
CREATE DATABASE testdb OWNER josef;
GRANT ALL ON DATABASE testdb TO josef;
CREATE ROLE
CREATE DATABASE
GRANT
retro=# \l testdb
List of databases
Name | Owner | Encoding | Locale Provider | Collate | Ctype
| ICU Locale | ICU Rules | Access privileges
--------+-------+----------+-----------------+-------------+-------------+------------+-----------+-------------------
testdb | josef | UTF8 | libc | cs_CZ.UTF-8 |
cs_CZ.UTF-8 | | | =Tc/josef +
| | | | |
| | | josef=CTc/josef
(1 row)

retro=# ALTER DATABASE testdb OWNER TO retro;
ALTER DATABASE
retro=# \l testdb
List of databases
Name | Owner | Encoding | Locale Provider | Collate | Ctype
| ICU Locale | ICU Rules | Access privileges
--------+-------+----------+-----------------+-------------+-------------+------------+-----------+-------------------
testdb | retro | UTF8 | libc | cs_CZ.UTF-8 |
cs_CZ.UTF-8 | | | =Tc/retro +
| | | | |
| | | retro=CTc/retro
(1 row)

It works exactly as described in this patch. +1
