Re: BUG #2096: bug in a SPI sample document

This documentation bug has been fixed. We currently have:

=> SELECT * FROM a;
x
---
1 -- no rows in a (0) + 1
(1 row)

=> INSERT INTO a VALUES (execq('SELECT * FROM a', 0) + 1);
INFO: EXECQ: 1
INSERT 0 1

Is the "INSERT 0 1" right? I see an oid in your example, but that might
be because we no longer user oids by default.
