[ blinks... ] It works for me in CVS tip ... [ time passes... ]
You're right though, it's busted in 7.3.*, and this was the fix:
2003-01-08 19:58 tgl
* src/include/catalog/pg_proc.h: Add missing pg_proc entry for
interval_scale(). The lack of this entry causes interval rounding
not to work as expected in 7.3, for example SELECT
'18:17:15.6'::interval(0) does not round the value. I did not
force initdb, but one is needed to install the added row.
We could backpatch this into the 7.3 branch, but it would only help
people who recompiled *and* re-initdb'd from the 7.3.3 sources. I
thought at the time it'd just create confusion to do that. I'm willing
to listen to other opinions though ...
