New certs give "could not accept SSL connection: sslv3 alert certificate unknow"

Hi everyone,

after swapping server and client certs and keys, I’m getting:
„could not accept SSL connection: sslv3 alert certificate unknown"
in the server logs.
CAcert has not changed.
Authentication with client certs is not configured.
If I remove .postgresql in the client home, everything works perfectly.

Only difference of the new certs is the ‚critical’ here:
X509v3 Key Usage: critical
Digital Signature, Key Encipherment, Data Encipherment
Can this be the reason?

Thanks, Axel
