Works for me: regression=# create schema ads; CREATE SCHEMA regression=# create table "ads"."MyTableName" (f1 int); CREATE TABLE regression=# select * from "ads"."MyTableName"; f1 ---- (0 rows) I'm wondering a bit about invisible white space in your schema name; but without a self-contained test case we can do no more than guess. regards, tom lane
