I'm looking for information on what it means: > DBD::Pg::db selectrow_array failed: FATAL: Socket command type I > unknown This looks to me like a protocol-level incompatibility: probably the client code is sending data in a slightly different format than the server is expecting, or one side or the other is off-by-one about message lengths, or something like that. One way or another the server is receiving an 'I' when it wasn't expecting that. I'm not aware of any such bugs on the server side in 7.3.4. What I suspect is a problem on the DBD::Pg side, where you did not specify what version you are using ... but if it's recent, it probably thinks that talking to 7.3.4 is a legacy problem ... regards, tom lane
