From 3695a555136a6d179cac8ae48d5f90171d5b30e9 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sun, 18 Dec 2011 15:49:00 -0500 Subject: Replace simple constant pg_am.amcanreturn with an AM support function. The need for this was debated when we put in the index-only-scan feature, but at the time we had no near-term expectation of having AMs that could support such scans for only some indexes; so we kept it simple. However, the SP-GiST AM forces the issue, so let's fix it. This patch only installs the new API; no behavior actually changes. --- src/backend/access/spgist/spgscan.c | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'src/backend/access/spgist/spgscan.c') diff --git a/src/backend/access/spgist/spgscan.c b/src/backend/access/spgist/spgscan.c index ac309649682..748265ecba7 100644 --- a/src/backend/access/spgist/spgscan.c +++ b/src/backend/access/spgist/spgscan.c @@ -559,3 +559,10 @@ spggettuple(PG_FUNCTION_ARGS) PG_RETURN_BOOL(false); } + +Datum +spgcanreturn(PG_FUNCTION_ARGS) +{ + /* Not implemented yet */ + PG_RETURN_BOOL(false); +} -- cgit v1.2.3
