Hmm ... It would appear that is it actually WSACleanup() that is taking
forever. I Added a WSAStartup() and a WSACleanup(), and it hung for awhile
on WSACleanup() instead of PQfinish() :)

Subject: [GENERAL] PQfinish blocking on non-existent IP address ...
/**********************************
How do I stop PQfinish from blocking?
(try any LAN IP address that doesn't exist on your LAN.)
I compiled it with both VC and MinGW, same result.
(change C:\Program Files (x86) to C:\Program Files for 32bit Windows OS)
Command Line Compile in VC 32bit:
cl x.cpp -I"C:\Program Files (x86)\PostgreSQL\8.4\include" -link "C:\Program
Files (x86)\PostgreSQL\8.4\lib\libpq.lib"
Command Line Compile in MinGW 32bit:
g++ x.cpp -o"x.exe" -I"C:\Program Files (x86)\PostgreSQL\8.4\include"
-L"C:\Program Files (x86)\PostgreSQL\8.4\lib" -llibpq
***********************************/
#include <stdlib.h>
#include <stdio.h>
#include <libpq-fe.h>
int main(int na,char** sa){
printf("Connecting ...\n");
PGconn* lpcn = PQconnectStart("dbname=postgres
host=192.168.250.60");
printf("Connected\n");
printf("Calling PQfinish\n");
PQfinish(lpcn);
printf("PQfinished\n");
return 0;
};
