From 108a0ec87d41393c362c5b8d8aa17d9a734e4f1a Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>

Subject: A little further progress on schemas: push down RangeVars into
 addRangeTableEntry calls.  Remove relname field from RTEs, since it will no
 longer be a useful unique identifier of relations; we want to encourage
 people to rely on the relation OID instead. Further work on dumping qual
 expressions in EXPLAIN, too.
