Not sure how other feel about that, but I am not really convinced that
we need two APIs. Saying that, having more control over the initial
size used for a StringInfo could provide better practices in some
cases. This reminds me of the ALLOCSET_SMALL_* fields in memutils.h,
hence an idea would be an initStringInfoExtended() that you could
combine with two #define two: one for the "default" of 1024 and a
second one for "small", like 32 or 64 (?), that can be used at will
with the new API call. Then you could switch initStringInfo() to
become a macro of the new "extended" call. Just an idea.
