+ Hi,
+
+
+ my patch is on my ftp and nobody works on it, but I mean it's good
+begin for some next work. I not sure with implement this experimental
+patch (but usable) to official sources. For example Jan has more complex
+idea about query plan cache ... but first time we must solve some
+sub-problems like memory management in shared memory that is transparently
+for starndard routines like copy query plan ... and Tom isn't sure with
+query cache in shared memory...etc. Too much queries, but less answers :-)
