Uh, well, we never call it ourselves, so if we don't expect other
applications to call it, why is it there?
Our code has:
/*
* Used to set callback that prevents concurrent access to
* non-thread safe functions that libpq needs.
* The default implementation uses a libpq internal mutex.
* Only required for multithreaded apps that use kerberos
* both within their app and for postgresql connections.
*/
typedef void (*pgthreadlock_t) (int acquire);
extern pgthreadlock_t PQregisterThreadLock(pgthreadlock_t newhandler);
We need to research why it was added.
