Our head of department basically put the kibosh on everyone's massive enthusiasm for migrating more and more MySQL systems to postgres, because once upon a time someone tried to run a schema change and postgres seemed to never be able to give the schema change the lock. We didn't really get told about the problem at the time, so we don't know much about what happened. And the anger-driven (anti) development seems like it's forever going to sit there, unresolved. Very frustrating situation for us.
