From e0c9301c87634f21c0a7c6305bdc6da15d6ba375 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 27 Jun 2001 23:31:40 +0000 Subject: Install infrastructure for shared-memory free space map. Doesn't actually do anything yet, but it has the necessary connections to initialization and so forth. Make some gestures towards allowing number of blocks in a relation to be BlockNumber, ie, unsigned int, rather than signed int. (I doubt I got all the places that are sloppy about it, yet.) On the way, replace the hardwired NLOCKS_PER_XACT fudge factor with a GUC variable. --- doc/src/sgml/runtime.sgml | 38 +++++++++++++++++++++++++++++++++++++- 1 file changed, 37 insertions(+), 1 deletion(-) (limited to 'doc/src') diff --git a/doc/src/sgml/runtime.sgml b/doc/src/sgml/runtime.sgml index 53add130cb1..d39d2d5d76f 100644 --- a/doc/src/sgml/runtime.sgml +++ b/doc/src/sgml/runtime.sgml @@ -1,5 +1,5 @@ @@ -1131,6 +1131,42 @@ dynamic_library_path = '/usr/local/lib:/home/my_project/lib:$libdir:$libdir/cont + + MAX_FSM_RELATIONS (integer) + + + Sets the maximum number of relations (tables) for which free space + will be tracked in the shared free-space map. + The default is 100.
