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 db3c4c3a2d98, 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.
