Обсуждение: to_char replacement

to_char() will still be around for dates, just not for intervals.  You
have nothing to worry about.

Eh?  Where did you get the idea that to_char() was going away?  The
documentation says that to_char(interval, text) is deprecated and
will be removed, but it says nothing about removing the function
altogether.

Raul is not the only one who misread that sentence.  I thought the same
thing when I read it last week.  Reading too quickly, I guess.  After
spending several minutes searching for a replacement function, I went back
a reread it, understanding it the second time.  Perhaps if
to_char(interval, text) were marked with (*) in table and then (*) note at
bottom, it would be clearer that this sentence does not apply to all arguments.

Agreed.  I think we were a little too concise in that statement. Here is
the updated wording:

      The 8.1 release will remove the <function>to_char()</> function
      for intervals.
