From f4122a8d50a56787770cb87e8269d6b48775ff4e Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Fri, 9 Jul 2010 14:06:01 +0000 Subject: Add a hook in ExecCheckRTPerms(). This hook allows a loadable module to gain control when table permissions are checked. It is expected to be used by an eventual SE-PostgreSQL implementation, but there are other possible applications as well. A sample contrib module can be found in the archives at: http://archives.postgresql.org/pgsql-hackers/2010-05/msg01095.php Robert Haas and Stephen Frost --- src/backend/executor/execMain.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'src/backend/executor/execMain.c') diff --git a/src/backend/executor/execMain.c b/src/backend/executor/execMain.c index 0b6cbcc4af..473fbcdae1 100644 --- a/src/backend/executor/execMain.c +++ b/src/backend/executor/execMain.c @@ -26,7 +26,7 @@ * * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/executor/execMain.c,v 1.349 2010/04/28 16:10:42 heikki Exp $ + * $PostgreSQL: pgsql/src/backend/executor/execMain.c,v 1.350 2010/07/09 14:06:01 rhaas Exp $ * *------------------------------------------------------------------------- */ @@ -63,6 +63,9 @@ ExecutorStart_hook_type ExecutorStart_hook = NULL; ExecutorRun_hook_type ExecutorRun_hook = NULL; ExecutorEnd_hook_type ExecutorEnd_hook = NULL; +/* Hook for plugin to get control in ExecCheckRTPerms() */ +ExecutorCheckPerms_hook_type ExecutorCheckPerms_hook = NULL; + /* decls for local routines only used within this module */ static void InitPlan(QueryDesc *queryDesc, int eflags); static void ExecEndPlan(PlanState *planstate, EState *estate); @@ -416,6 +419,9 @@ ExecCheckRTPerms(List *rangeTable) { ExecCheckRTEPerms((RangeTblEntry *) lfirst(l)); } + + if (ExecutorCheckPerms_hook) + (*ExecutorCheckPerms_hook)(rangeTable); } /* -- cgit v1.2.1
