You must not have enabled EXEC_BACKEND properly. It's a compile-time
#define that affects multiple modules, so it's easy to get wrong.
The way I usually turn it on is
make distclean
./configure ... options of choice ...
edit src/include/pg_config.h, add "#define EXEC_BACKEND" line
make, install, test
In this way the setting is persistent till the next distclean/configure
cycle.
