From d1bc3525c072a4c6bbc7bbba5da68cd30adfd1a6 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 25 Mar 2010 15:50:22 +0000 Subject: [PATCH] Fix ginint4_queryextract() to actually do what it was intended to do for an unsatisfiable query, such as indexcol && empty_array. It should return -1 to tell GIN no scan is required; but silly typo disabled the logic for that, resulting in unnecessary "GIN indexes do not support whole-index scans" error. Per bug report from Jeff Trout. Back-patch to 8.3 where the logic was introduced. --- contrib/intarray/_int_gin.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/contrib/intarray/_int_gin.c b/contrib/intarray/_int_gin.c index 6856a68e038..37ea55b8d1f 100644 --- a/contrib/intarray/_int_gin.c +++ b/contrib/intarray/_int_gin.c @@ -57,7 +57,7 @@ ginint4_queryextract(PG_FUNCTION_ARGS) } } - if (nentries == 0) + if (*nentries == 0) { switch (strategy) {
