Q2/2026 Server Maintenance
Description
We got a dataset that contains indexed virtual columns, suddenly it started crashing at start and this seems related judging by the stack trace below.
We are unable to get replicas built from the master because after successful prepare of the backup, the server crashes at start.
Stack trace below, we do have a core file for that.
Program terminated with signal SIGSEGV, Segmentation fault.
