From 82b37765c76b8b2daf6cad3dfb5e5b4a2776d56f Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Fri, 16 Oct 2015 11:37:19 -0400 Subject: Fix a problem with parallel workers being unable to restore role. check_role() tries to verify that the user has permission to become the requested role, but this is inappropriate in a parallel worker, which needs to exactly recreate the master's authorization settings. So skip the check in that case. This fixes a bug in commit 924bcf4f16d54c55310b28f77686608684734f42. --- src/backend/access/transam/parallel.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'src/backend/access/transam/parallel.c') diff --git a/src/backend/access/transam/parallel.c b/src/backend/access/transam/parallel.c index e09bdb20b0d..9c7428f5d6c 100644 --- a/src/backend/access/transam/parallel.c +++ b/src/backend/access/transam/parallel.c @@ -96,6 +96,9 @@ int ParallelWorkerNumber = -1; /* Is there a parallel message pending which we need to receive? */ bool ParallelMessagePending = false; +/* Are we initializing a parallel worker? */ +bool InitializingParallelWorker = false; + /* Pointer to our fixed parallel state. */ static FixedParallelState *MyFixedParallelState; @@ -815,6 +818,9 @@ ParallelWorkerMain(Datum main_arg) char *tstatespace; StringInfoData msgbuf; + /* Set flag to indicate that we're initializing a parallel worker. */ + InitializingParallelWorker = true; + /* Establish signal handlers. */ pqsignal(SIGTERM, die); BackgroundWorkerUnblockSignals(); @@ -942,6 +948,7 @@ ParallelWorkerMain(Datum main_arg) * We've initialized all of our state now; nothing should change * hereafter. */ + InitializingParallelWorker = false; EnterParallelMode(); /* -- cgit v1.2.3
