Apparently, because of the way the wrappers work, having -lpthread on libpq.so does NOT add it to the NEEDED list.
I made the following patch, and all compiles now:
Yes, I was afraid of that. Is there any way to make it work? If not, evey libpq program you create will need -lpthread added.I think we need to mention if you --enable-thread-safety you MUST use -lpthread on UnixWare, at least. I don't know about other platforms.
I'll ask the compiler guys, but I suspect we're going to have to do it this way.
The a.out (not any library) should be linked with -Kpthread (not -lpthread).
This will force libthread to be linked in the right order relative to
libc, libC, networking libraries, etc.
In other words, the entire application either is or is not linked with threads; it's not a property of an individual library.
SO, IF we are using the threads flags, we need to use them on ALL libpq-using programs, ours or the users.
