The slash in the slash command gets escaped too...:

#include <stdio.h>
#include "libpq-fe.h"

main() {
char *s, *r;

s = "\\d";

printf("%s\n", s);

r = (char *) malloc(strlen(s) * 2);
PQescapeString(r, s, strlen(s));

printf("%s\n", r);

if(strcmp(r, "\\\\d") == 0) {
printf("match\n");
}

free(s);
free(r);
}

Without \\\\ tab expansion for slash commands doesn't work.

There may of course be better ways of solving this problem.
