How to tell what OS PostgreSQL is installed on.

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.
