From e09b48316c22fce727bce3c89fa64fc627787e6a Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Fri, 27 Mar 2015 23:35:16 +0200 Subject: Add index-only scan support to btree_gist. inet, cidr, and timetz indexes still cannot support index-only scans, because they don't store the original unmodified value in the index, but a derived approximate value. --- contrib/btree_gist/btree_float4.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'contrib/btree_gist/btree_float4.c') diff --git a/contrib/btree_gist/btree_float4.c b/contrib/btree_gist/btree_float4.c index 6a1db380eaf..13dc4a5c0f0 100644 --- a/contrib/btree_gist/btree_float4.c +++ b/contrib/btree_gist/btree_float4.c @@ -16,6 +16,7 @@ typedef struct float4key ** float4 ops */ PG_FUNCTION_INFO_V1(gbt_float4_compress); +PG_FUNCTION_INFO_V1(gbt_float4_fetch); PG_FUNCTION_INFO_V1(gbt_float4_union); PG_FUNCTION_INFO_V1(gbt_float4_picksplit); PG_FUNCTION_INFO_V1(gbt_float4_consistent); @@ -116,6 +117,13 @@ gbt_float4_compress(PG_FUNCTION_ARGS) PG_RETURN_POINTER(gbt_num_compress(entry, &tinfo)); } +Datum +gbt_float4_fetch(PG_FUNCTION_ARGS) +{ + GISTENTRY *entry = (GISTENTRY *) PG_GETARG_POINTER(0); + + PG_RETURN_POINTER(gbt_num_fetch(entry, &tinfo)); +} Datum gbt_float4_consistent(PG_FUNCTION_ARGS) -- cgit v1.2.3
