No, we should use CSIDL_APPDATA. Two reasons:
1) Never put things in the root of the profile :P
2) CSIDL_APPDATA is supported on 9x (4.71 of the shell which,IIRC, is
Win95, as long as you have IE4 or newer install. And I doubt a lot of
people don't have that). Remember that our *client side code* support
9x.
(Then of course it should have "postgresql" (or ".postgresql" for
consiscency with *nix) appended to it)
Also, SHGetFolderPath() rqeuires Win2k. There is
SHGetSpecialFolderPath() for all versions.

Don't trust $HOME on win32. There is no such thing.It's set by Cygwin,
and it's set by the MingW shell, but it's not set by Windows. HOMEDRIVE,
HOMEPATH and HOMESHARE are set, but not HOME.
You can trust USERPROFILE in NT based OSes. Not sure about 9x. Using the
API above is a much nicer way of doing it.
So, a quick implementation (not tested, but shouldn't be too hard) of
your functino would be:
static bool pqGetHomeDirectory(char *buf, int bufsize)
{
char tmppath[MAX_PATH+16]; /* Add 16 chars for "/.postgresql/"
*/
ZeroMemory(tmppath,sizeof(tmppath));
if (!SHGetSpecialFolderPath(NULL, tmppath, CSIDL_APPDATA,
FALSE)) {
return FALSE;
strcat(tmppath,"/.postgresql/");
if (strlen(tmppath) > bufsize)
return FALSE; /* Better than returning a chopped-off
path */
strcpy(buf, tmppath);
return TRUE;
}
You're going to have to add #include <shlobj.h> to the file as well.
