The default of 4GB is too low for a production setup and causes
DependencyTrack to hit java.lang.OutOfMemoryError. This causes
Dependency Track to enter a weird state where it will throw 502 and
504 errors.
The initial 4GB was set to make Dependency Track run in the (too
small) VM in the NixOS integration test. Move the explicit heap
configuration there. For the service itself, we now don't set a limit.
This means the JVM will choose its maximum heap on its own, which does
a much better job for realistic scenarios.
I added a release note, because people who run Dependency Track on
very tiny VMs/machines may experience issues.
This avoids restarting the postgresql server, when only ensureDatabases
or ensureUsers have been changed. It will also allow to properly wait
for recovery to finish later.
To wait for "postgresql is ready" in other services, we now provide a
postgresql.target.
