for pg_migrator, per suggestion from Magnus.

in their display of command-line options with other client applications.

proper default username.

its sole caller does that too.  Jan Matousek, via Pavel Stehule

comparing the same column to multiple values.

match the behavior of autovacuum, which does this as the xid advances
even if autovacuum is turned off.

hardcoding a 'template0' check, per suggestion from Alvaro.

This might fix a problem where someone has allowed 'template0'
connections, but it is a cleaner approach even if doesn't fix the
bug.

Modify path separators for Win32.

Per ideas from Takahiro Itagaki

EDB must maintain their own patch set for this.

Should fix buildfarm failures.

* There is no chmod() on Windows.
* Must always use the 3-parameter version of open()
* There is no dynloader.h - but it also appears unnecessary on all platforms
* Don't include shlobj.h because it causes compile errors, and from what I can
  see it's not actually used. This may need to be added back for mingw
  and/or cygwin in the worst case.

(pg_upgrade_support).

on the buildfarm.

cmp parameter for pg_scandir().  The code failed to support this anyway
for Sun/Windows, so pretending we could accept a parameter other than
NULL was just asking for trouble.

Add PGAPPICON to all executable makefiles.

Add documentation.

Supports migration from PG 8.3 and 8.4.

rather than returning NULL for some-but-not-all failures as they used to.
Remove now-redundant tests for NULL from call sites.

We had to do something about this because many call sites were failing to
check for NULL; and changing it like this seems a lot more useful and
mistake-proof than adding checks to the call sites without them.

Two of these were pointed out by Erik Rijkers; the rest I found.

Make dmetaphone.c safe for pgindent and fussy compilers. Still to do: make it properly encoding aware w.r.t. chars U+00C7 and U+00D1.

reasonably promptly, by adding CHECK_FOR_INTERRUPTS in the per-page loops.
