The contents of command.c, creatinh.c, define.c, remove.c and rename.c have been divided according to the type of object manipulated - so ALTER TABLE code is in tablecmds.c, aggregate commands in aggregatecmds.c and so on. A few common support routines remain in define.c (prototypes in src/include/commands/defrem.h). No code has been changed except for includes to reflect the new files. The prototypes for aggregatecmds.c, functioncmds.c, operatorcmds.c, and typecmds.c remain in src/include/commands/defrem.h. From John Gray <jgray@azuli.co.uk>

#ifndef PORTALCMDS_H

#include "utils/portal.h"
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.
