Обсуждение: Bug #947: time(timenow()) Parse Error

Aaron Silver (silvera@ngt-dev.com) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
time(timenow()) Parse Error

Long Description
In using Postgres 7.2.2 on a client's system I received a parse error using time(timenow()). Either in a function or
viaa command-line "select time(timenow());" statement, I received a "parse error near timenow". A "select
date(timenow());"worked fine. Doing "select time('2003-04-15 00:00:00');" worked fine also. 

This was not an issue on a machine running Postgres 7.1.3.

Is/was this a known issue? Is there a patch, or in what release was this fixed?

The syntax time(something) is now taken as a type name per SQL spec.
You need to write this with explicit cast syntax, or else put quotes
around "time":

    select now()::time;
    select cast(now() as time);
    select "time"(now());

Although I'm wondering whether you shouldn't just be using

    select current_time;

Note that the variants with timenow() run into a similar problem, which
is that the "time"(abstime) function has got the same mistake
internally.  I'm surprised no one noticed this for two whole releases...
