In typeconv.sgml we have an example:
tgl=> select (4.3 !);
?column?
----------
24
(1 row)
However, actually it does not work:
test=# select (4.3 !);
ERROR: Unable to identify a postfix operator '!' for type 'double precision'
You may need to add parentheses or an explicit cast
Shall we correct the doc or is that a bug?
