I got curious — how did people even catch viruses on their computers? Was it something a friend sent? Or maybe they downloaded a cracked game or some shady program? Share your stories — would be interesting to read.

We recently had a funny problem. Our service ran fine, but a postgres upgrade failed because some pg internals were broken (broken ref ids). Dumping the DB also failed for the same error. Reading and writing was still fine, though. So we restored backup after backup… no dice. They all had the same issue: it was working for the service but we couldn’t perform any maintenance. Ultimately we had to “manually” dump the data of the service and replay it into a fresh db. That took quite long. But that was interesting, since even the verification of the backups didn’t help us notice that kind of corruption.
I have had to do similar with a db at my job.
Backups passed verification but we had a lot of weird issues, like queries getting stuck, or not returning records that were definitely there.
Ended up having to manually recreate the schema and import records from a manual data dump because something in the db file itself was messed up.
