RE: libpq @windows : leaked singlethread_lock makes AppVerifier unhappy

[Першин Юрий Петрович]

Hi
Here is my workaround (from unit_tests.dll DLL_PROCESS_DETACH):

            //3. Destroy LIBPQ!static pthread_mutex_t singlethread_lock
-                              327                     HMODULE hLeakedLibPQ = 
::GetModuleHandleA("libpq.dll"); //libpq.dll v13.0.1.20323 
(https://ftp.postgresql.org/pub/odbc/versions/msi/psqlodbc_13_00_0000.zip)
-                              328                     if (hLeakedLibPQ) {
-                              329                         void 
**singlethread_lock_ptr = (void **)(((BYTE *)hLeakedLibPQ) +
-                              330         #ifdef _WIN64
-                              331                             0x484b8
-                              332         #else
-                              333                             0x3F26C
-                              334         #endif //_WIN64
-                              335                             );

-                              338                             typedef 
void(*pthread_mutex_destroy)(void *mutex);
-                              339                             
pthread_mutex_destroy freemtx = 
(pthread_mutex_destroy)::GetProcAddress(hLeakedLibPQ, "PQfreemem");
-                              340                             assert(freemtx
