Yes, security. In any case for what you are trying to do the server
configuration is not something the client has to fool with.

It is important to remember that SSL is not provided by Postgres, it
just has the ability to use SSL to make a connection. So it just
piggybacks on an existing program. In doing that it makes certain
assumptions to start with.

For server side:

http://www.postgresql.org/docs/9.3/static/ssl-tcp.html


For libpq clients:

http://www.postgresql.org/docs/9.3/static/libpq-ssl.html

Important the above is for libpq based clients such as psql. I am not
sure how non-libpq clients such as the Postgres JDBC client handle this.

The beginning assumptions can be modified by setting environment
variables(again this is for libpq clients):

http://www.postgresql.org/docs/9.3/static/libpq-envars.html

or the postgresql.conf

http://www.postgresql.org/docs/9.3/static/runtime-config-connection.html#RUNTIME-CONFIG-CONNECTION-SECURITY

For information on what search_path really does see:

http://www.postgresql.org/docs/9.3/static/runtime-config-client.html
