New PostgrSQL Errors

Hi All,

Suddenly, I'm getting a lot of this sort of thing in my Apache log for
Bricolage:

message type 0x54 arrived from server while idle
message type 0x44 arrived from server while idle
message type 0x43 arrived from server while idle
message type 0x5a arrived from server while idle

WHERE p.id = o.pref__id AND p.value = o.value AND p.id =

Any idea what those messages are and why they'd be hosing my statement
handles? FWIW, the statement handle _should_ be executing; execute() is
called five lines before the error is generated in Pref.pm line 1314.

TIA,
