If you know how this problem might be fixed, list the solution below:
- ---------------------------------------------------------------------

Traced it to a SEGV in postgresql-6.4.2/src/backend/nodes/outfuncs.c
in the function _outResdom (line 671). The node->resname pointer was
NULL leading to an explosion of the sprintf statement (kinda hard to
do a sprintf of a string with a null pointer as the argument :-) Quick
hack to fix is:

sprintf(buf, "\"%s\"", node->resname ? node->resname : ""); /* fix for SELECT col AS

instead of:

sprintf(buf, "\"%s\"", node->resname); /* fix for SELECT col AS

Why/how we are actually getting a NULL pointer in that field I didn't
track down (since this hack fixed the problem).
