Обсуждение: Built in function question

Does anyone know if there is a function that can return the path to the
data directory?

I was looking through the docs, but could not find anything.

Thanks,

In 8.0 and later,
    SHOW data_directory;
or the equivalent function call.

            regards, tom lane

 I found it in the pg_settings view, but if there is another way I would
like to know about it.

Thanks,

Tony

As Tom aluded, you can also do this:

regression=# select current_setting('data_directory');
       current_setting
---------------------------
  /usr/local/pgsql-8.0/data
(1 row)
