This is pretty hard to believe, and I couldn't duplicate it in a simple test:
(I followed the variant with a private certificate authority.)
2. Copy certificate and key into $PGDATA/server.crt & server.key, setting appropriate file permissions.
3. Edit postgresql.conf to set "ssl = on", touching nothing else.
4. "pg_ctl reload", check server log to verify that it turned SSL on. (On older PG versions you might need "pg_ctl restart".)
5. Probe with "openssl s_client".
The certificate returned to s_client is visibly the same one I put into server.crt. openssl fails to verify it, but that's no surprise since I didn't tell openssl to trust the private certificate authority.
I speculate that you forgot to do "pg_ctl reload" after modifying the server.crt file, or some similar error. If you can really reproduce this problem, please present an exact reproduction recipe, and tell us the PG version too.
