Bitbucket Server FATAL: missing support function 1 for attribute 1 of index "pg_opclass_oid_index"

[Daniel Einars]

Hi

I'm getting an error when trying to launch bitbucket server using the official bitbucket docker image.

019-05-01 22:07:32,146 ERROR [spring-startup] com.zaxxer.hikari.pool.HikariPool bitbucket - Exception during pool initialization.

This started happening today. I've tried finding similar post but to no avail.

I've tried running different version of bitbucket, restoring backups from the entire server to before the fatal exception  appeared, all to no avail.

Is all my data lost?

I used an external database and have backups of it, but even creating a clean config bitbucket server and linking it to the database listed the same error when attempting to connect to it. Have there been any breaking changes lately?
