Jeff Davis 5c31669058 Re-validate connection string in libpqrcv_connect().
A superuser may create a subscription with password_required=true, but
which uses a connection string without a password.

Previously, if the owner of such a subscription was changed to a
non-superuser, the non-superuser was able to utilize a password from
another source (like a password file or the PGPASSWORD environment
variable), which should not have been allowed.

This commit adds a step to re-validate the connection string before
connecting.
