Wiki page list does not work on PostgreSQL
Created by: lightoze
Created one page and edited it once, then "/wikis/pages" view tries to execute this erroneous SQL:
# SELECT "wikis".* FROM "wikis" WHERE "wikis"."project_id" = 16 GROUP BY slug ORDER BY created_at;
ERROR: column "wikis.id" must appear in the GROUP BY clause or be used in an aggregate function
Which results in 500 error page.
