From 15c121b3ed7eb2f290e19533e41ccca734d23574 Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Tue, 30 Sep 2008 10:52:14 +0000 Subject: Rewrite the FSM. Instead of relying on a fixed-size shared memory segment, the free space information is stored in a dedicated FSM relation fork, with each relation (except for hash indexes; they don't use FSM). This eliminates the max_fsm_relations and max_fsm_pages GUC options; remove any trace of them from the backend, initdb, and documentation. Rewrite contrib/pg_freespacemap to match the new FSM implementation. Also introduce a new variant of the get_raw_page(regclass, int4, int4) function in contrib/pageinspect that let's you to return pages from any relation fork, and a new fsm_page_contents() function to inspect the new FSM pages. --- src/backend/bootstrap/bootstrap.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/backend/bootstrap/bootstrap.c') diff --git a/src/backend/bootstrap/bootstrap.c b/src/backend/bootstrap/bootstrap.c index 0689fb1f1a..04194acd3f 100644 --- a/src/backend/bootstrap/bootstrap.c +++ b/src/backend/bootstrap/bootstrap.c @@ -8,7 +8,7 @@ * Portions Copyright (c) 1994, Regents of the University of California * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/bootstrap/bootstrap.c,v 1.245 2008/09/01 20:42:43 tgl Exp $ + * $PostgreSQL: pgsql/src/backend/bootstrap/bootstrap.c,v 1.246 2008/09/30 10:52:11 heikki Exp $ * *------------------------------------------------------------------------- */ @@ -33,7 +33,6 @@ #include "postmaster/bgwriter.h" #include "postmaster/walwriter.h" #include "storage/bufmgr.h" -#include "storage/freespace.h" #include "storage/ipc.h" #include "storage/proc.h" #include "tcop/tcopprot.h" @@ -419,7 +418,6 @@ AuxiliaryProcessMain(int argc, char *argv[]) case StartupProcess: bootstrap_signals(); StartupXLOG(); - LoadFreeSpaceMap(); BuildFlatFiles(false); proc_exit(0); /* startup done */ -- cgit v1.2.1
