The rest of buildfarm was OK with it too, but I learned of a small
problem through CI testing of another patch: it's not OK for
src/port/pwrite.c to do this:
if (part > 0)
elog(ERROR, "unexpectedly wrote more than requested");
... because now when I try to use pg_pwrite() in pg_test_fsync,
Windows fails to link:
libpgport.lib(pwrite.obj) : error LNK2019: unresolved external symbol
errstart referenced in function pg_pwritev_with_retry
[C:\projects\postgresql\pg_test_fsync.vcxproj]
I'll go and replace that with an assertion.
