Good afternoon,

If I backup a PostgreSQL 10.14 database using pg_dump from Version
11.10, and restore to Version 11, the comment for the database is lost.

I haven't encountered this before when upgrading between major versions.

Test case:

C:\Program Files\PostgreSQL\10\bin>psql
psql (10.14)

postgres=# CREATE DATABASE test_comment TEMPLATE = template0;
CREATE DATABASE
postgres=# COMMENT ON DATABASE test_comment IS 'Test Comment Database';
COMMENT
postgres=# SELECT pg_catalog.shobj_description(d.oid, 'pg_database') as
"Version"
postgres-# FROM pg_catalog.pg_database d
postgres-#   where d.datname = 'test_comment';
        Version
-----------------------
 Test Comment Database
(1 row)

C:\Program Files\PostgreSQL\11\bin>pg_dump -h localhost -p 5433 -U
postgres -f "G:\test_comment.bak" -Fc -O test_comment

C:\Program Files\PostgreSQL\11\bin>psql -p 5435
psql (11.10)

postgres=# CREATE DATABASE test_comment TEMPLATE = template0;
CREATE DATABASE
postgres=# \q

C:\Program Files\PostgreSQL\11\bin>pg_Restore -p 5435  -U postgres -d
test_comment "G:\test_comment.bak"

C:\Program Files\PostgreSQL\11\bin>psql -p 5435
psql (11.10)

postgres=# SELECT pg_catalog.shobj_description(d.oid, 'pg_database') as
"Version"
postgres-# FROM pg_catalog.pg_database d
postgres-#   where d.datname = 'test_comment';
 Version
---------

(1 row)

What am I missing?

Thanks,
George
