I have cleaned up some areas, but now cost_index() is getting that
problem with temp as NaN because it has exceeded it's range or something
strange like that.
Does psql \do work on stock 6.5?
Here is the weird part. This is with no optimization, and of course the
assert at the end fails on the test temp >= 0. Breakpoint 1, cost_index (indexid=17033,
expected_indexpages=137251568, selec=0.00877192989, relpages=2, reltuples=114, indexpages=2, indextuples=114,
is_injoin=1'\001') at costsize.c:132132 Cost temp = 0;(gdb) n134 if
(!_enable_indexscan_&& !is_injoin)(gdb) 142 if (expected_indexpages <= 0)(gdb) 144 if
(indextuples<= 0)(gdb) print temp$1 = 0(gdb) n148 temp += expected_indexpages;(gdb) print temp$2 = 0(gdb)
n156 temp += ceil(((double) selec) * ((double) relpages));(gdb) print temp$3 = -NaN(0x400000)(gdb) print
expected_indexpages$4= 137251568
