History
Michael Paquier e5f3839af6 Switch buffile.c/h to use pgoff_t instead of off_t 
off_t was previously used for offsets, which is 4 bytes on Windows,
hence limiting the backend code to a hard limit for files longer than
2GB.  This leads to some simplification in these files, removing some
casts based on long, also 4 bytes on Windows.

This commit removes one comment introduced in db3c4c3a2d, not relevant
anymore as pgoff_t is a safe 8-byte alternative on Windows.

This change is surprisingly not invasive, as the callers of
BufFileTell(), BufFileSeek() and BufFileTruncateFileSet() (worker.c,
tuplestore.c, etc.) track offsets in local structures that just to
switch from off_t to pgoff_t for the most part.

The file is still relying on a maximum file size of
MAX_PHYSICAL_FILESIZE (1GB).  This change allows the code to make this
maximum potentially larger in the future, or larger on a per-demand
basis.
