More cleanups to appendStringInfo() usage in node/outfuncs.c.

Jan

more cleanups...of note, appendStringInfo now performs like sprintf(),
where you state a format and arguments.  the old behavior required
each appendStringInfo to have to have a sprintf() before it if any
formatting was required.

Also shortened several instances where there were multiple appendStringInfo()
calls in a row, doing nothing more then adding one more word to the String,
instead of doing them all in one call.

Initial attempt to clean up the code...

Switch sprintf() to snprintf()
Remove any/all #if 0 -or- #ifdef NOT_USED -or- #ifdef FALSE sections of
	code

EXPLAIN all indices used.

a backend core dump, because it was concatenating a potentially long
string onto another string that didn't necessarily have enough room.
Shame, shame.

        Fixes  a  bug  in  the rule system that caused a crashing
        backend when a join-view with calculated column  is  used
        in subselect.

        Modifies  EXPLAIN to explain rewritten queries instead of
        the plain SeqScan on a view. Rules can produce very  deep

Another PGINDENT run that changes variable indenting and case label indenting.  Also static variable indenting.
