Обсуждение: pg_dump UDT/function dependency patch

Patch to put rudimentary dependency support into pg_dump. This addresses
the UDT/function order problem. Unfortunately, this is not a small patch so
I would prefer some debate about whether it should be applied 7.1.

 *        - Rudimentary support for dependencies in archives. Current
implementation
 *              uses dependencies to modify the OID used in sorting TOC
entries.
 *              This will NOT handle multi-level dependencies, but will
manage simple
 *              relationships like UDTs & their functions.
 *
 *        - Treat OIDs with more respect (avoid using ints, use macros for
 *              conversion & comparison).

Looks good to me.  A large part of the bulk appears to be changes to
not treat OIDs as integers, which is a necessary bug fix anyway.

One small stylistic quibble:

+#define oidcmp(x,y) ( (x < y ? -1 : (x > y) ?  1 : 0))
+#define oideq(x,y) (x == y)

These need more parentheses to be safe:

+#define oidcmp(x,y) ( ((x) < (y) ? -1 : ((x) > (y)) ?  1 : 0))
+#define oideq(x,y) ((x) == (y))

            regards, tom lane
