-- Regression test to Global Temporary Table implementation
--
-- This test is not part of the regression tests run with
-- make check install because it need manual changes.
--
-- Test for extension privilege to use non-superuser role.
-- For this test the extension must have been registered as
-- a plugin to allow simple user to use LOAD of the extension.
-- See Installation instruction in documentation for details.
-- Then execute:
--
--    createdb gtt_privilege
--    LANG=C psql -d gtt_privilege -f test/privilege.sql > results/privilege.out 2>&1
--    diff results/privilege.out test/expected/privilege.out
--    dropdb gtt_privilege
--    dropuser pgtt_user1

-- As superuser
CREATE ROLE pgtt_user1 LOGIN;

-- Import the library
LOAD '$libdir/plugins/pgtt';
