description |
While upgrading to Ubuntu 19.04, the release upgrader removed postgresql-10. To make matters worse, apt/dpkg did NOT ask whether the databases should be kept and simply removed all of them.
I believe this is due to removal_blacklist.cfg containing ^postgresql-.*[0-9]\.[0-9].*, which does not match newer releases such as postgresql-10 as it expects an X.Y version scheme. Something like ^postgresql-.*[0-9].* should probably be added in addition. |
[Impact]
Users who choose to autoremove packages can have postgresql-10 removed which during its purge will drop the cluster and its databases.
[Test Case]
On a cosmic system
1) install postgresql-10 and ubuntu-release-upgrader-core
2) create a test database using psql - create database junk;
3) fill that database with junk using pgbench e.g. pgbench -in -s10 junk
4) verify you have data in /var/lib/postgresql - du -sh /var/lib/postgresql/*
5) run do-release-upgrade
6) choose to automatically remove packages (watch postgresql-10 get removed)
7) observe you have no more data in /var/lib/postgresql
With the version of the release upgrader in -proposed postgresql-10 will not be removed, postgresql-11 will not be installed and you'll still have your data.
[Regression Potential]
The regex could be too generic and prevent some other packages from being removed so look at it closely.
