Hi, <p>I had to install pgsql 6.3.2. because of compatibility reasons. <br />The compiling part finishes without any problemsand the html-access to the <br />database works, too. <br />The problem is - I cannot start the frontend psql andhave following <br />error messages: <br /> Connection to database 'postgres' failed. <br /> Unsupportedfrontend protocol. <p>I've never come across any of these messages before. Does anyone know what <br />they mean?I have tried to compile pgsql with other templates, but no <br />success...:( <p>I'd be grateful for any help... <p>Regards<br /><a href="mailto:drechsel@glamus.de">Dirk Drechsel</a><br /><a href="mailto:webmaster@glamus.de">WebMaster</a><br/><a href="http://www.glamus.de/">Glamus GmbH</a><br />

The protocol that frontend applications (relying on libraries) use has changed some time around 6.4. The message probably means that the frontend applications are linked with the newer libraries, and your old 6.3.2 database can't understand them. Herouth -- Herouth Maoz, Internet developer.

You'll need to use a 6.3.2 psql (or at least a 6.3.2 libpq) to talk to your old server. The newer servers still talk to old clients, but not vice versa... regards, tom lane
