CREATE/ALTER/DROP USER MAPPING are now allowed either by the server owner or
by a user with USAGE privileges for his own user name.  This is more or less
what the SQL standard wants anyway (plus "implementation-defined")

Hide information_schema.user_mapping_options.option_value, unless the current
user is the one associated with the user mapping, or is the server owner and
the mapping is for PUBLIC, or is a superuser.  This is to protect passwords.

Also, fix a bug in information_schema._pg_foreign_servers, which hid servers
using wrappers where the current user did not have privileges on the wrapper.
The correct behavior is to hide servers where the current user has no
privileges on the server.

equally (in glibc: et_EE, sv_SE, tk_TM).  It turns out that this was
already taken care of previously by select_1.out, which I had forgotten to
update for an unrelated change.  But might as well avoid the issue
altogether.

locales (da_DK, fo_FO, kl_GL, nb_NO, nn_NO in glibc) sort "aa" after "z".

"cg" and "ci".  This eliminates a test failure on the following glibc
locales: br_FR, cs_CZ, cy_GB, es_EC, es_US, hsb_DE, ig_NG, ik_CA, sk_SK.

array types for composite types.  Although pg_dump understood it wasn't
supposed to dump these array types as separate objects, it must include
them in the dependency ordering analysis, and it was improperly assigning them
the same relatively-high sort priority as regular types.  This resulted in
effectively moving composite types and tables up to that same high priority,
which broke any ordering requirements that weren't explicitly enforced by
dependencies.  In particular user-defined operator classes, which should come
out before tables, failed to do so.  Per report from Brendan Jurd.

In passing, also fix an ill-considered decision to give text search objects
the same sort priority as functions and operators --- the sort result looks
a lot nicer if different object types are kept separate.  The recent
foreign-data patch had copied that decision, making the sort ordering even
messier :-(

PLy_exception_set, and clarify some error messages.

Replace leftover instances of _() by ecpg_gettext(), the latter being the
correct way to refer to the library's message catalog, instead of the one of
the program using the library.

Drop NLS support for ecpg_log(), which is a debugging instrument similar to
elog() in the backend.

We cannot support NLS in the ecpg compatlib, because that requires
ecpg_gettext, which is in ecpglib, which is not a dependency of compatlib.  It
doesn't seem worthwhile to worry about this, since the only translatable
string is "out of memory", and gettext probably won't be able to do much
without memory either.

rewritten into an UPDATE.

Back-patch to 8.3 and 8.2. For HEAD, Tom suggested inventing a new
SPI_OK_REWRITTEN return code, but that's not a backportable solution. I'll
do that as a separate patch, this patch will do as a stopgap measure for HEAD
too in the meanwhile.

It's not possible to do CREATE DATABASE inside a transaction, so previously
we just got a server error instead.

Backpatch to 8.2, which is where the -1 feature appeared.

now always use the system username as the default, and not try to pick it up
from the kerberos ticket.

This fixes the spurious error messages that show up on kerberos-enabled builds
when not actually using kerberos, and puts it in line with how other authentication
methods work.
