The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/10/release-10-7.html
Description:
Following is our finding:
Postgres query behaves differently in 2 version
Specifically
(json_agg(DISTINCT table_name.*) filter(where table_name is not null)) as
table,
.
.
.
gives null record in 10.7 where it gives proper data in 10.6
Following is the version difference of postgres

4.8.3 20140911 (Red Hat 4.8.3-9), 64-bit
NOT WORKING - PostgreSQL 10.7 on x86_64-pc-linux-gnu, compiled by gcc (GCC)
