I have looked over the patch and it seems fine, though I am concerned
about the abort() case with no output.  I realize stderr might be going
nowhere, but in fe-print.c we do an fprintf(stderr) for memory failures
so for consistency I think we should do the same here.  If there is
concern about code bloat, I suggest a macro at the top of the file for
thread failure exits:

    #define THEAD_FAILURE(str) \
    do { \
        fprintf(stderr, libpq_gettext("Thread failure:  %s\n")); \
        exit(1); \
    } while(0)
