Re: How to tell what OS PostgreSQL is installed on.

Hi Scott,

Thanks for the info. I did tried

select pg_show_all_settings()

But this function has a filter based on a user privilege. As postgres
user, I got 187 rows return and can see parameter like data_directory with
its OS path. But as a non admin user, I got 176 rows return and all the
parameters that would point to a directory on the OS are not shown due to
privilege.

Louis.

Another option might be to look in the
select pg_show_all_settings() for the ident_file.

If the ident file is a DOS path (aka c:\somewhere\some dir\some file), you
know you're on a Windows-based system. If it's a UNIX path, select
version()
will tell you specifically.

Hi,

I have a need to find out what OS PostgreSQL is running under. I need to
be
able to query the database or send a command and figure it out. I also
do
not have super user permission to do this. All I want to know is if the
PostgreSQL I am connected to is running from Windows or Non Windows.

I could do "Show data_directory" and parse the result, but this require
superuser permission.

I tried select version() also. Under Windows OS, I got this:

version

---------------------------------------------------

PostgreSQL 8.3.6, compiled by Visual C++ build 1400

Does anyone know if Visual C++ is use to only compile PostgreSQL for
Windows? Or can other compiler be use? If Visual C++ is always use for
Windows and Windows only then this is very good information I can use.

I know on RedHat, I got this.

version

--------------------------------------------------------------------------
--
--------------------------

PostgreSQL 8.3.7 on i686-redhat-linux-gnu, compiled by GCC gcc (GCC)
3.4.6
20060404 (Red Hat 3.4.6-10)

And on Solaris I got this.

-----------------

PostgreSQL 8.1.11 on sparc-sun-solaris2.10, compiled by
/ws/on10-tools/SUNWspro/SOS8/bin/cc -Xa

(1 row)

Thank you all in advance for your help.
