Обсуждение: Bug #696: timestamp function does not work?

Sandor, Vig (sandor.vig@audi.hu) reports a bug with a severity of 2
The lower the number the more severe it is.

Short Description
timestamp function does not work?

Long Description
I've wrote an application under PHP, wich uses Postgres 7.1.
After I installed the new RedHat 7.3 with Postgres 7.2 some of my
SQLs didn't worked. Mainly thoose, with the timestamp function:

  timestamp(current_date, current_time)

does work under 7.1 but under 7.2 there is an parser error!
Why?

Sample Code
select current_date; O.K.
select current_time; O.K.
select current_timestamp; O.K.
select timestamp(current_date, current_time); Works only under 7.1!!!!

No file was uploaded with this report

Please check the release notes and the SQL standard for why you can not
call a function timestamp() directly; the syntax is now reserved for
specifying a data type, not a function call.

For this particular case, you should be using the SQL-standard
CURRENT_TIMESTAMP.

You can convert date, time to timestamp by casting date to timestamp and
then adding the time.

You're gonna have to rename the function.  Sorry.

(Actually, you could double quote it instead: "timestamp"(foo,bar)
but the path of least resistance is to choose a name that is not
an SQL reserved word.)
