Subject: Add needed #include.
X-Git-Tag: REL_12_BETA1~1192
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=cb09903fe63132a35e4b217bc394882b05c0c6f3;p=postgresql

Add needed #include.

Per POSIX, WIFSIGNALED and related macros are provided by <sys/wait.h>.
Apparently on Linux they're also pulled in by some other inclusions,
but BSD-ish systems are pickier.  Fixes portability issue in ffa4cbd62.

Per buildfarm.
