(possibly (un)translated) letters that are actually expected as input.
Also reject invalid responses instead of silenty taken them as "no".

and there's only one place that's a kluge, ie, appendStringLiteralConn.
Note that pg_dump itself doesn't use appendStringLiteralConn, so its
behavior is not affected; only the other utility programs care.
o turns off escape_string_warning in pg_dumpall.c
o optionally use E'' for \password (undocumented option?)
o honor standard_conforming-strings for \copy (but not
support literal E'' strings)
o optionally use E'' for \d commands
o turn off escape_string_warning for createdb, createuser,
droplang
and standard_conforming_strings; likewise for the other client programs
that need it. As per previous discussion, a pg_dump dump now conforms
to the standard_conforming_strings setting of the source database.
We don't use E'' syntax in the dump, thereby improving portability of
the SQL. I added a SET escape_strings_warning = off command to keep
the dumps from getting a lot of back-chatter from that.
'off'. This allows pg_dump output with standard_conforming_strings =
'on' to generate proper strings that can be loaded into other databases
without the backslash doubling we typically do. I have added the
dumping of the standard_conforming_strings value to pg_dump.
I also added standard backslash handling for plpgsql.
as per my recent proposal. For now the template data is hard-wired in
proclang.c --- this should be replaced later by a new shared system
catalog, but we don't want to force initdb during 8.1 beta. This change
lets us cleanly load existing dump files even if they contain outright
wrong information about a PL's support functions, such as a wrong path
to the shared library or a missing validator function. Also, we can
revert the recent kluges to make pg_dump dump PL support functions that
are stored in pg_catalog.
While at it, I removed the code in pg_regress that replaced $libdir
with a hardcoded path for temporary installations. This is no longer
needed given our support for relocatable installations.
into pg_catalog rather than public, and supports dumping languages whose
handlers are found there. This will make it easier to drop the public
schema if desired.
Unlike the previous patch, the comments have been updated and I have
reformatted some code to meet Alvarro's request to stick to 80 cols. (I
actually aghree with this - it makes printing the code much nicer).
I think I did the right thing w.r.t versions earlier than 7.3, but I
have no real way of checking, so that should be checked by someone with
more/older knowledge than me ;-)

unlike template0 and template1 does not have any special status in
terms of backend functionality. However, all external utilities such
as createuser and createdb now connect to "postgres" instead of
template1, and the documentation is changed to encourage people to use
"postgres" instead of template1 as a play area. This should fix some
longstanding gotchas involving unexpected propagation of database
objects by createdb (when you used template1 without understanding
the implications), as well as ameliorating the problem that CREATE
DATABASE is unhappy if anyone else is connected to template1.
Patch by Dave Page, minor editing by Tom Lane. All per recent
pghackers discussions.
