Well, you can say things like:
char * const *ptr
Which means that *ptr is const, but ptr and **ptr are not. Each of
those can be made const/not const as desired...
What is intended here is quite a different question, the use of pointers
in that part of psql is a bit haphazard at times. FWIW, Coverity
complains about stuff here too, but I just marked it all WONTFIX :).
Have anice day,
