[Tatsuo Ishii]

Fix test failure of extended-query-test/disable-load-balance-while-function.data.

The test failed because CREATE function propagation to standby took a while.
To fix this, add "SELECT pg_sleep(5)" to wait for standby synced with primary.
Also expected file is updated to reflect this.
2) CREATE function propagation to standby took a while
