Andreas Brandl	988dc80585	Further remove code branches by database type ... We dropped MySQL support and a lot of mysql specific code has been removed in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/29608. This comes in from the other direction and removes any `if postgresql?` branches.	2019-07-29 12:47:06 +02:00
Stan Hu	5c8ce94052	Fix statement timeouts in RemoveRestrictedTodos migration ... On GitLab.com, the RemoveRestrictedTodos background migration encountered about 700+ failures a day due to statement timeouts. PostgreSQL might perform badly with a LIMIT 1 because the planner is guessing that scanning the index in ID order will come across the desired row in less time it will take the planner than using another index. The order_hint does not affect the search results. For example, `ORDER BY id ASC, updated_at ASC` means the same thing as `ORDER BY id ASC`.
