Hi Kirk,

FYI there are a couple of compiler errors reported:

Windows compiler:

contrib/pg_visibility/pg_visibility.c(400): error C2143: syntax error
: missing ')' before '{'
[C:\projects\postgresql\pg_visibility.vcxproj]

GCC:

storage.c: In function ‘RelationTruncate’:
storage.c:238:14: error: variable ‘newnblocks’ set but not used
[-Werror=unused-but-set-variable]
  BlockNumber newnblocks = InvalidBlockNumber;
              ^
storage.c:237:14: error: variable ‘new_nfsmblocks’ set but not used
[-Werror=unused-but-set-variable]
  BlockNumber new_nfsmblocks = InvalidBlockNumber;
              ^
