Not as far as we can tell - one of my DB team noticed it day before yesterday - there were no tell tale signs of any issues but we have seen issues yesterday with certain records not being found

All servers used to be en_US as I think that was the default and had been setup early in our use of PG. I suspect our devops guy corrected this during the upgrade.

>Have you logged into the production instance using psql and tried the queries to see if they work?
Not via psql, but as I said we saw issues from our app layer. I will do a similar test with psql and let you know
