Quite a few buildfarm members are not happy about the initialization
that 9a8dd2c5a added to PendingBackendStats.  For instance [1]:

gcc -std=gnu99 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Werror=vla -Wendif-labels
-Wmissing-format-attribute-Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -g -O2 -I. -I.
-I../../../../src/include -D_GNU_SOURCE -I/usr/include/libxml2   -c -o pgstat_backend.o pgstat_backend.c 
pgstat_backend.c:39:1: warning: missing braces around initializer [-Wmissing-braces]
 static PgStat_BackendPending PendingBackendStats = {0};
 ^
pgstat_backend.c:39:1: warning: (near initialization for \342\200\230PendingBackendStats.pending_io\342\200\231)
[-Wmissing-braces]

I guess that more than one level of braces is needed for this to
be fully correct?  Similar from ayu, batfish, boa, buri, demoiselle,
dhole, rhinoceros, shelduck, siskin.
