We had previously (af26857a)
established the U.S. spellings as standard.

XLOG_XACT_COMMIT_COMPACT leaves out invalidation messages and relfilenodes,
saving considerable space for the vast majority of transaction commits.
XLOG_XACT_COMMIT keeps same definition as XLOG_PAGE_MAGIC 0xD067 and earlier.

Add rel.h to some files that now need it.

The previous coding was ugly, as it marked special tokens as such in the
wrong stage, relying on workarounds to figure out if they had been
quoted in the original or not.  This made it impossible to have specific
keywords be recognized as such only in certain positions in HBA lines,
for example.  Fix by restructuring the parser code so that it remembers
whether tokens were quoted or not.  This eliminates widespread knowledge
of possible known keywords for all fields.

Also improve memory management in this area, to use memory contexts that
are reset as a whole instead of using retail pfrees; this removes a
whole lotta crufty (and probably slow) code.

Instead of calling strlen() three times in next_field_expand on the
returned token to find out whether there was a comma (and strip it),
pass back the info directly from the callee, which is simpler.

In passing, update historical artifacts in hba.c API.

Fill in the collation columns of the views attributes, columns,
domains, and element_types.  Also update collation information in
sql_implementation_info.

This lays the groundwork for an upcoming patch to streamline the
handling of DROP commands.

WAL records of type XLOG_BTREE_REUSE_PAGE were generated using a
latestRemovedXid one higher than actually needed because xid used was
page opaque->btpo.xact rather than an actually removed xid.

Since the names try_relation_openrv() and try_heap_openrv() don't seem
quite appropriate, rename the functions to relation_openrv_extended()
and heap_openrv_extended().  This is also more general, if we have a
future need for additional parameters that are of interest to only a
few callers.

This is infrastructure for a forthcoming patch to allow
get_object_address() to take a missing_ok argument as well.

Patch by me, review by Noah Misch.

My previous attempt was quite a bit less than half-baked with respect to
heap_update().

As noted by Christian Ullrich.

It's been like this since HOT was originally introduced, but the logic
is complex enough that this is a recipe for bugs, as we've already
found out with SSI.  So refactor heap_hot_search_buffer() so that it
can satisfy the needs of index_getnext(), and make index_getnext() use
that rather than duplicating the logic.

This change was originally proposed by Heikki Linnakangas as part of a
larger refactoring oriented towards allowing index-only scans.  I
extracted and adjusted this part, since it seems to have independent
merit.  Review by Jeff Davis.

DEF_PGPORT already comes in from pg_config.h, so we don't need to pass
it in again with a -D option.  Apparently a leftover from the shell
script conversion.

This doesn't actually change the resulting set of strings, but better
be correct.

The --flag argument can be used to tell xgettext the arguments of
which functions should be flagged with c-format in the PO files,
instead of guessing based on the presence of format specifiers, which
fails if no format specifiers are present but the translation
accidentally introduces one.

Appropriate flag settings have been added for each message catalog.

Put gettext trigger words that are common to the backend and backend
modules into a makefile variable to include everywhere, to avoid
error-prone repetitions.

Since it's globally defined in c.h, it should be treated as a gettext
trigger everywhere.

It currently doesn't make a difference, but it's inconsistent with
most other usage, and it might interfere with a future patch, so I'll
change it all in a separate commit.

Also, replace tabs with spaces for alignment.

s/const//g wasn't exactly what I was suggesting here ... parameter
declarations of the form "const structtype *param" are good and useful,
so put those occurrences back.  Likewise, avoid casting away the const

backend/Makefile was treating errcodes.h as a header always generated
during build, but actually it's a header provided in tarballs.  Hence,

Per bug #6072 from Hartmut Raschick.

It's not entirely stable.

Per suggestion from Josh Kupershmidt.

As Tom Lane pointed out, "const Relation foo" doesn't guarantee that you
can't modify the data the "foo" pointer points to. It just means that you
can't change the pointer to point to something else within the function,
which is not very useful.
