Ugh. In the case of worker_spi it's because -fvisibility=hidden isn't applied
to worker_spi.c at all. Which in turn is because Makefile.shlib isn't used at
all for MODULES= style modules just for MODULE_big= ones :(.
Once that's "fixed" it fails as expected...
I'm not sure what the best way to deal with this is. Just now I copied the
logic from Makefile.shlib to pgxs.mk (by the existing CFLAGS_SL use), but that
doesn't scale - there's other direct uses of CFLAGS_SL.
Perhaps the best way would be to add the -fvisibility=hidden to CFLAGS_SL, and
work around the explicit exports issue in Makefile.shlib by adding an explicit
-fvisibility=default? Or perhaps CFLAGS_SL
The easiest solution would be to change worker_spi's Makefile to use
MODULE_big.
There are already many cases where MODULE_big is used instead of MODULES
for seemingly random reasons, so I wouldn't worry too much about it here
if it helps you move forward.
