+ elog(DEBUG1, "CreateFileMapping(%Iu) with SEC_LARGE_PAGES failed " + "due to insufficient large pages, huge pages disabled", + size); Amit is right, you had better use %zu as we do in all the other places of the code dealing with Size variables that are printed. When compiling with Visual Studio, Postgres falls back to the implementation of sprintf in src/port/snprintf.c so that's not something to worry about. -- Michael -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
