Clear the OpenSSL error queue before cryptohash operations Setting up an EVP context for ciphers banned under FIPS generate two OpenSSL errors in the queue, and as we only consume one from the queue the other is at the head for the next invocation:
postgres=# select md5('foo'); ERROR: could not compute MD5 hash: unsupported postgres=# select md5('foo'); ERROR: could not compute MD5 hash: initialization error Clearing the error queue when creating the context ensures that we don't pull in an error from an earlier operation.
