Great. Always happy to add one more notch to our pistol :)

This seems consistant with 'current' coming up zero, since datetime is
stored as a double float in seconds from 2000-01-01. Don't know why that
would be, but you might want to enable debugging print statements in
backend/utils/adt/dt.c by doing the following:
1) edit the Makefile in that directory to add
CFLAGS += -DDATEDEBUG
2) do a "make clean" in that directory, then rebuild your executables.
3) run postmaster from a window, so you can see the results of print
statements.
4) connect a psql session from another window, and try some sample
queries like your failed ones above. The print statements might give you
some clues if you follow them through the code in a third window :)
Let me know if you get any evidence...
