pgsql: Prevent memory leaks in our various bison parsers when an error

От

Log Message:
-----------
Prevent memory leaks in our various bison parsers when an error occurs
during parsing.  Formerly the parser's stack was allocated with malloc
and so wouldn't be reclaimed; this patch makes it use palloc instead,
so that flushing the current context will reclaim the memory.  Per
Marko Kreen.
