Portability hack for pg_global_prng_state.

2021年11月29日 05:04:45 +0000 (00:04 -0500)

PGDLLIMPORT is only appropriate for variables declared in the backend,
not when the variable is coming from a library included in frontend code.
(This isn't a particularly nice fix, but for now, use the same method
employed elsewhere.)
