Greetings,

I'm reposting this question since I received zero replies from my
original post (maybe the original subject line was misleading).

I've just^W upgraded from PostgreSQL 7.1.2 to 7.3.2.

In 7.1.2 I was able to use the output of time(2) (and the like) to
insert into a field of timestamp type.

First thing i noticed with the upgrade was that the following broke:

  in 7.1.2
  => select timestamp ( 1046923200 );
      timestamp        
  ------------------------
   2003-03-05 20:00:00-08
  (1 row)

  in 7.3.2
  => select timestamp ( 1046923200 );
  ERROR:  TIMESTAMP(1046923200) precision must be between 0 and 6


Can anyone point me to a work-around?

I notice that I can use abstime( 1046923200 ) to get the desired
result.  But is this the optimal way to do this?


My client application uses mktime(3) and then forms the SQL
statement to insert into a table of the form:

  sprintf( sql_stmt,
           "insert  into tab1 "
           "        ( ... , target_timestamp, ... ) "
           "values  ( ... , timestamp( %lu ), ... ) ",
           ...,
           mktime( &tm ) );
           /*
            * You get the idea.
            */

Thanks in advance,

sidster
