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.
