Displaying a journal entry and joining with main table - postgresql

Question

I have a journal system that has a table structure like:
[journal_logs]
id
title
created_at
[journal_entries]
id
journal_log_id
body
created_at
So a "journal_log" is made up of one or more "entries".
On my webpage I want to list the most recent logs, along with the entries.
Example:
"Log 10"
"entry 1"
"entry 2"
"entry 3"
"Log 9"
"entry 1"
"Log 8"
"entry 1"
"entry 2"
Is it possible to produce an output like this with a single query?

Answer 1

here is example with <UL><LI>
data sample:
t=# create table journal_logs(id int,title text);
CREATE TABLE
t=# create table journal_entries(id int,journal_log_id int);
CREATE TABLE
t=# insert into journal_logs select 8,'a';
INSERT 0 1
t=# insert into journal_logs select 9,'a';
INSERT 0 1
t=# insert into journal_logs select 10,'a';
INSERT 0 1
t=# insert into journal_entries select 1,8;
INSERT 0 1
t=# insert into journal_entries select 2,8;
INSERT 0 1
t=# insert into journal_entries select 1,9;
INSERT 0 1
t=# insert into journal_entries select 1,10;
INSERT 0 1
t=# insert into journal_entries select 2,10;
INSERT 0 1
t=# insert into journal_entries select 3,10;
INSERT 0 1
query sample:
t=# with p as (
select concat('<ul>',l.id,l.title) ul,concat('<li>',e.id) li
from journal_logs l
join journal_entries e on l.id = journal_log_id
)
select
concat(
case when li = min(li) over (partition by ul order by li) then ul end
,concat(li, case when li = max(li) over (partition by ul) then '</ul>' end)) html
from p;
html

<ul>10a<li>1
<li>2
<li>3</ul>
<ul>8a<li>1

(6 rows)
