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.

Zero out the pointer fields of PGresult so that these mistakes are more

'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.

infelicities, try to un-break ecpg to the best of my ability. (It's not clear
how ecpg is going to find out the setting of standard_conforming_strings,
though.) I think pg_dump still needs work, too.

dump ordering, for ease of comparing outputs from different installations.

performance gains might ensue from reducing XLOG_BLCKSZ. In any case

to fix regressions introduced in the recent patch adding additional
\connect options. This is based on work by Volkan YAZICI, although
this version of the patch doesn't bear much resemblance to Volkan's
version.
\connect takes 4 optional arguments: database name, user name, host
name, and port number. If any of those parameters are omitted or
specified as "-", the value of that parameter from the previous
connection is used instead; if there is no previous connection,
the libpq default is used. Note that this behavior makes it
impossible to reuse the libpq defaults without quitting psql and
restarting it; I don't really see the use case for needing to do
that.

DROP OWNED BY is actually a bit kludgy, but it seems better to do it this way

during parse analysis, not only errors detected in the flex/bison stages.
This is per my earlier proposal. This commit includes all the basic
infrastructure, but locations are only tracked and reported for errors
involving column references, function calls, and operators. More could
be done later but this seems like a good set to start with. I've also
moved the ReportSyntaxErrorPosition logic out of psql and into libpq,
which should make it available to more people --- even within psql this
is an improvement because warnings weren't handled by ReportSyntaxErrorPosition.

This fixes a known bug where psql does not prompt for a password on some
Win32 systems.

make use of the recently added ability to create a shell type explicitly.
I also put in place some infrastructure to allow dump/no dump decisions
to be made separately for each database object, rather than the former
hardwired 'dump if in a dumpable schema' policy. This was needed anyway
for shell types so now seemed a convenient time to do it. The flexibility
isn't exposed to the user yet, but is ready for future extensions.
by decompiling the typdefaultbin expression, not just printing the typdefault
text which may be out-of-date or assume the wrong schema search path. (It's
the same hazard as for adbin vs adsrc in column defaults.) The catalogs.sgml
spec for pg_type implies that the correct procedure is to look to
typdefaultbin first and consider typdefault only if typdefaultbin is NULL.
I made dumping of both domains and base types do that, even though in the
current backend code typdefaultbin is always correct for domains and
typdefault for base types --- might as well try to future-proof it a little.
Per bug report from Alexander Galler.
up a bunch of the support utilities.
In src/backend/utils/mb/Unicode remove nearly duplicate copies of the
UCS_to_XXX perl script and replace with one version to handle all generic
files. Update the Makefile so that it knows about all the map files.
This produces a slight difference in some of the map files, using a
uniform naming convention and not mapping the null character.
In src/backend/utils/mb/conversion_procs create a master utf8<->win
codepage function like the ISO 8859 versions instead of having a separate
handler for each conversion.
There is an externally visible change in the name of the win1258 to utf8
conversion. According to the documentation notes, it was named
incorrectly and this changes it to a standard name.
Running the Unicode mapping perl scripts has shown some additional mapping
changes in koi8r and iso8859-7.

I looked into this and it seems the problem is that the view doesn't
get flattened into the main query because of the has_nullable_targetlist
limitation in prepjointree.c. That's triggered because pg_roles has
'********'::text AS rolpassword
which isn't nullable, meaning it would produce wrong behavior if
referenced above the outer join.
Ultimately, the reason this is a problem is that the planner deals only
in simple Vars while processing joins; it doesn't want to think about
expressions. I'm starting to think that it may be time to fix this,
because I've run into several related restrictions lately, but it seems
like a nontrivial project.
In the meantime, reducing the LEFT JOIN to pg_roles to a JOIN as per
Peter's suggestion seems like the best short-term workaround.

ReportSyntaxErrorPosition could probably do with more smarts about
handling control characters, for the moment I'll just get it back to
handling tabs consistently.
comments on cluster global objects like databases, tablespaces, and
roles.
It touches a lot of places, but not much in the way of big changes. The
only design decision I made was to duplicate the query and manipulation
functions rather than to try and have them handle both shared and local
comments. I believe this is simpler for the code and not an issue for
callers because they know what type of object they are dealing with.
This has resulted in a shobj_description function analagous to
obj_description and backend functions [Create/Delete]SharedComments
mirroring the existing [Create/Delete]Comments functions.

(optionally) to a new host and port without exiting psql. This
eliminates, IMHO, a surprise in that you can now connect to PostgreSQL
on a differnt machine from the one where you started your session. This
should help people who use psql as an administrative tool.

Currently, while \e saves a single statement as one entry, interactive
statements are saved one line at a time. Ideally all statements
would be saved like \e does.

If the second output column value is 'a\nb', the 'b' should appear
in the second display column, rather than the first column as it
does now.

BACKWARD COMPATIBLE CHANGE.
The only user-visible change I saw in the regression tests is that a
SELECT * on a table where all the columns have been dropped doesn't
return a blank line like before. This seems like a step forward.

not print the owner name in the object comment.
eg:
--
-- Name: actor; Type: TABLE; Schema: public; Owner: chriskl; Tablespace:
--
Becomes:
--
-- Name: actor; Type: TABLE; Schema: public; Owner: -; Tablespace:
--
This makes it far easier to do 'user independent' dumps. Especially for
distribution to third parties.

The original decision to print something for each subdirectory was made

the return expression was complex.

a little bit, and set the minimum buffers-per-connection ratio to 10 not

that the tests can be twiddled independently, and added some documentation
