No, we are expecting them to have pthread_*.
On UnixWare, to get the pthread_* functions, you need to invoke a compiler
option (-Kpthread), to cause libpthread to be linked in.
Since libpq.so now REQUIRES the function, we need to either:
1) force ANY program that uses libpq to be compiled/linked with -Kpthread
or
2) dynamically determine if libpthread is loaded and use the real pthread_*
functions if they are there (libpthread is in the image), or use fake
singlethread versions of the pthread_* calls if libpthread is NOT in the
image.
