exactly at the point where we need to insert a new item, the calculation used
the wrong size for the "high key" of the new left page.  This could lead to
choosing an unworkable split, resulting in "PANIC: failed to add item to the
left sibling" (or "right sibling") failure.  Although this bug has been there
a long time, it's very difficult to trigger a failure before 8.2, since there
was generally a lot of free space on both sides of a chosen split.  In 8.2,
where the user-selected fill factor determines how much free space the code
tries to leave, an unworkable split is much more likely.  Report by Joe
Conway, diagnosis and fix by Heikki Linnakangas.

Allow args to spi_prepare to be standard type aliaes as well as those known in pg_type. Fixes bug #2917. Add some regression tests for these cases.

see if it makes the buildfarm happy...

- Add new SQL command SET XML OPTION (also available via regular GUC) to
  control the DOCUMENT vs. CONTENT option in implicit parsing and
  serialization operations.

- Subtle corrections in the handling of the standalone property in
  xmlroot().

- Allow xmlroot() to work on content fragments.

- Subtle corrections in the handling of the version property in
  xmlconcat().

- Code refactoring for producing XML declarations.

page about the maximum UTF8 sequence length we support (4 bytes since 8.1,
3 before that).  pg_utf2wchar_with_len never got updated to support 4-byte
characters at all, and in any case had a buffer-overrun risk in that it
could produce multiple pg_wchars from what mblen claims to be just one UTF8
character.  The only reason we don't have a major security hole is that most
callers allocate worst-case output buffers; the sole exception in released
versions appears to be pre-8.2 iwchareq() (ie, ILIKE), which can be crashed
due to zeroing out its return address --- but AFAICS that can't be exploited
for anything more than a crash, due to inability to control what gets written
there.  Per report from James Russell and Michael Fuhr.

Pre-8.1 the risk is much less, but I still think pg_utf2wchar_with_len's
behavior given an incomplete final character risks buffer overrun, so
back-patch that logic change anyway.

This patch also makes sure that UTF8 sequences exceeding the supported
length (whichever it is) are consistently treated as error cases, rather
than being treated like a valid shorter sequence in some places.

involving unions of types having typmods.  Variants of the failure are known
to occur in 8.1 and up; not sure if it's possible in 8.0 and 7.4, but since
the code exists that far back, I'll just patch 'em all.  Per report from
Brian Hurt.

For converting error codes to messages, we only need to cover those codes
that we raise ourselves now.
