Bruce Momjian	41477b9a83	This patch makes two minor fixes to the docs: (1) fixes a ... spelling mistake in the PREPARE ref page (2) Makes some English more consistent, in the ref pages for some of the client apps (3) Adds a link to the libpq docs in the vacuumdb ref page.

Tom Lane	aa83bc04e0	Restructure parsetree representation of DECLARE CURSOR: now it's a ... utility statement (DeclareCursorStmt) with a SELECT query dangling from it, rather than a SELECT query with a few unusual fields in it. Add code to determine whether a planned query can safely be run backwards. If DECLARE CURSOR specifies SCROLL, ensure that the plan can be run backwards by adding a Materialize plan node if it can't. Without SCROLL, you get an error if you try to fetch backwards from a cursor that can't handle it. (There is still some discussion about what the exact behavior should be, but this is necessary infrastructure in any case.) Along the way, make EXPLAIN DECLARE CURSOR work.	2003-03-10 03:53:52 +00:00
