Hi,
just committed some fixes to get back the old "<>" for NULL
strings on nodeToString().
Marc's recent changes to appendStringInfo() handling broke
it. The old version converted a NULL string into a "<>".
Handing a NULL for %s to vsnprintf() is implementation
dependent (some put nothing, some put (null) and some might
simply crash - but none puts "<>").
There is a new macro stringStringInfo(s) in include/lib.h
which checks for NULL and substitutes by "<>". All string
arguments to appendStringInfo() are now embedded into that
(also in commands/explain.c).
Regression tests for select_views, rules and plpgsql are O.K.
again.
Jan
