RE: [EXTERNAL] Re: Can you install/run postgresql on a FIPS enabled host?

So the logs for one of our Java servers that is attempting to connect to postgres is showing:

Notice that the last "Caused by" is showing the "Unsupported PBKDF2 for SCRAM-SHA-256".  We are also using Hibernate so perhaps the underlying problem is there?

java.sql.SQLException: Connections could not be acquired from the underlying database!

We do test that case from time to time, but not regularly.

It sounds like something thinks that scram-sha-256 encryption is disallowed by FIPS.  That may or may not be accurate.  If it's supposed to be allowed, you'd need to poke a little harder to narrow down where the problem is.

(Digging in our commit logs, it looks like version 14.2 has some changes that might make this work better than it did in older versions; but I can't tell from the log messages whether the issue being fixed was new-in-14 or not.)
