From d4a611e94a3b4504f034fdb31a8ab4a72955b887 Mon Sep 17 00:00:00 2001 From: Peter Geoghegan Date: Thu, 5 Jan 2017 11:29:53 -0800 Subject: [PATCH 2/2] Reduce MAX_PHYSICAL_FILESIZE value to BLCKSZ This constant controls the size of underlying fd.c managed files that the BufFile abstraction multiplexes for its callers. A very low value for the constant can be useful for flushing out bugs. --- src/backend/storage/file/buffile.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/backend/storage/file/buffile.c b/src/backend/storage/file/buffile.c index 7ebd636..ac3e400 100644 --- a/src/backend/storage/file/buffile.c +++ b/src/backend/storage/file/buffile.c @@ -47,7 +47,7 @@ * The reason is that we'd like large temporary BufFiles to be spread across * multiple tablespaces when available. */ -#define MAX_PHYSICAL_FILESIZE 0x40000000 +#define MAX_PHYSICAL_FILESIZE BLCKSZ #define BUFFILE_SEG_SIZE (MAX_PHYSICAL_FILESIZE / BLCKSZ) /* -- 2.7.4
