For backwards compatibility with earlier versions of PostgreSQL, if a
root CA file exists, the behavior of
<literal>sslmode</literal>=<literal>require</literal> will be the same
- as that of <literal>verify-ca</literal>, meaning the sever certificate
+ as that of <literal>verify-ca</literal>, meaning the server certificate
is validated against the CA. Relying on this behavior is discouraged,
and applications that need certificate validation should always use
<literal>verify-ca</literal> or <literal>verify-full</literal>.
