0x1a8510f2	51ab0a8ccf	Fix moderncsqlite errors and rebase onto main (#2832) ... This is #2819 but rebased on latest `main`. This PR is against main too as opposed to the `moderncsqlite` branch. The main change here is simply: ```go // add query parameters to the dsn if strings.Contains(dsn, "?") { dsn += "&" } else { dsn += "?" } // wait some time before erroring if the db is locked // https://gitlab.com/cznic/sqlite/-/issues/106#note_1058094993 dsn += "_pragma=busy_timeout%3d10000" ``` ### Pull Request Checklist <!-- Please read https://matrix-org.github.io/dendrite/development/contributing before submitting your pull request --> * [x] I have added tests for PR _or_ I have justified why this PR doesn't need tests. * [x] Pull request includes a [sign off below using a legally identifiable name](https://matrix-org.github.io/dendrite/development/contributing#sign-off) _or_ I have already signed off privately Signed off privately.

Neil Alexander	ebd137cf6b	Check PostgreSQL connection count (#2760) ... This PR queries PostgreSQL for the `max_connections` and `superuser_reserved_connections` settings and then ensures that Dendrite's `max_open_conns` doesn't exceed the allowed value. This is a really common source of configuration problems and can either result in blocking queries or deadlocks, so it seems reasonable that we complain as loudly as possible when it happens.	2022-10-05 11:07:17 +01:00
