I think that this is not a great idea. I think that we should do away
with the GUC, but keep the function hstore_print() so we can pretty
print that way. I don't believe that this falls afoul of the usual
obvious reasons for not varying the behavior of IO routines with a
GUC, since it only varies whitespace, but it is surely pretty
questionable to have this GUC's setting vary the output of hstore_out,
an IMMUTABLE function.
