Maybe.

In other words, pqTraceOutputMessage recognizes message id and calls
the function corresponding one-on-one to the id. So the functions
knows what is the message type of myself and there's no reason for
pqTraceOutputMessage to print the message type on its behalf.
+ pqTraceOutputR(const char *message, FILE *f)
+ {
+ int cursor = 0;
+
+ pqTraceOutputInt32(message, &cursor, f);
I don't understand the reason for spliting message and &cursor here.
+ pqTraceOutputR(const char *message, FILE *f)
+ {
+ char *p = message;
+
+ pqTraceOutputInt32(&p, f);
works well.
+/* RowDescription */
+static void
+pqTraceOutputT(const char *message, int end, FILE *f)
+{
+ int cursor = 0;
+ int nfields;
+ int i;
+
+ nfields = pqTraceOutputInt16(message, &cursor, f);
+
+ for (i = 0; i < nfields; i++)
+ {
+ pqTraceOutputString(message, &cursor, end, f);
+ pqTraceOutputInt32(message, &cursor, f);
+ pqTraceOutputInt16(message, &cursor, f);
+ pqTraceOutputInt32(message, &cursor, f);
+ pqTraceOutputInt16(message, &cursor, f);
+ pqTraceOutputInt32(message, &cursor, f);
+ pqTraceOutputInt16(message, &cursor, f);
+ }
+}
I didn't looked closer, but lookong the usage of the variable "end",
something's wrong in the function.
regards.
