Subject: Fix direct access to Relation->rd_indpred.
X-Git-Tag: REL9_4_BETA1~1307
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=405a468b02dd80a069b95c4eb9838cb6a562eddd;p=postgresql

Fix direct access to Relation->rd_indpred.

Should use RelationGetIndexPredicate(), since rd_indpred is just a cache
that is not computed until/unless demanded.  Per buildfarm failure on
CLOBBER_CACHE_ALWAYS animals; diagnosis and fix by Hitoshi Harada.
