i am trying to write a SQL function that determines if the Postgres Server is running on windows, is that possible, or is there a way to get the platform of a running Server?

    select version() will include that information (although a bit hard to parse)

  • That's probably the best you will get with SQL. Use PL/Perl or PL/Python for something better.

You can simply use select version()

I tried it on an Linux Alpine server (through a Docker container) and got this:

test=> select version();



                                             version                                             
-------------------------------------------------------------------------------------------------
PostgreSQL 9.6.8 on x86_64-pc-linux-musl, compiled by gcc (Alpine 6.2.1) 6.2.1 20160822, 64-bit
(1 row)


You can have more informations on postgres system informations functions here https://www.postgresql.org/docs/current/functions-info.html



Hope it'll help you !

This is the code I wroteand used at the end, it works great on Postgres 11 version:



CREATE OR REPLACE FUNCTION GetPLatform()
RETURNS varchar
AS
$$
declare platform varchar;
begin
SELECT CASE
WHEN OSVersion.OS LIKE '%w64%' THEN 'windows'
WHEN OSVersion.OS LIKE '%w32%' THEN 'windows'
WHEN OSVersion.OS LIKE '%mingw%' THEN 'windows'
WHEN OSVersion.OS LIKE '%visual studio%' THEN 'windows'
WHEN OSVersion.OS LIKE '%linux%' THEN 'linux'
WHEN OSVersion.OS LIKE '%mac%' THEN 'mac'
ELSE
'UNKNOWN'
END into platform
FROM (SELECT
substr(substr(version(), strpos(version(), ' on ')+3), 1,
strpos(substr(version(), strpos(version(), ' on ')+3),
', compiled by')-1) as OS)
as OSVersion;
return platform;
end;
$$
LANGUAGE PLPGSQL;

select GetPLatform()


You can adjust it as you want for other platforms...
