Обсуждение: Win32 version question

In phpPgAdmin, I need to know if the backend supports tablespaces or 
not.  What is the most reliable way of detecting that the backend is the 
win32 native version and hence does not support tablespaces?  Version 
string info?

Or alternatively, what is the most direct way of detecting its presence 
or absence, regardless of backend OS?

Check the uptime...if it's greater than 7 days, it's not win32 :).

Seriously, you can check the version() string.  If it's got mingw init,
it's win32 native.

So it can't be compiled by other compiler?  Say Digital Mars or some
Microsoft or Borland compiler?

Nope. It needs the GNU tool set.

Does the win32 build have a pg_tablespace table? are there any rows in
it? 

Was thinking the combination of the two queries would be able to
determine table space support in some fashion:

select * from pg_class where relnamespace = (select oid from
pg_namespace where nspname = 'pg_catalog') and relname =
'pg_tablespace';

select count(*) from pg_tablespace ;

select count(*) from pg_tablespace;
works normally, but you can do something like this:

You can do this:
test=# create tablespace ts location 'c:/temp';
ERROR:  tablespaces are not supported on this platform
test=#
