I noticed an incorrect example in doc/src/sgml/func.sgml...

brent=# SELECT EXTRACT(SECOND FROM TIME '17:12:28.5');date_part 
-----------       28
(1 row)

The documentation says this should return 28.5.  Digging a bit, I
noticed the following (discrepancy?).  Is this desired behavior?

brent=# select "time"('12:00:12.5');   time     
-------------12:00:12.50
(1 row)

brent=# select '12:00:12.5'::time;  time   
----------12:00:12
(1 row)

IMO, one of these needs to be fixed before RC1 is rolled.


On a similar note, it would be neat if there was an sgml tag like <examplequery> SELECT EXTRACT(SECOND FROM TIME
'17:12:28.5');</examplequery>
 
that would dynamically execute the query and insert the result in
the sgml file...  This would ensure the docs always agree with current
behavior ;-)

cheers. brent
