up by quotes or backslashes in words that are being matched to database
names (per gripe from Ian Barwick, though I didn't use his patch).
Also fix possible memory leakage if _complete_with_query isn't run to
completion (not clear if that can happen or not, but be safe).
sequence every time it's called is bogus --- it interferes with user
control over the seed, and actually decreases randomness overall
(because a seed based on time(NULL) is pretty predictable). If you really
want a reproducible result from geqo, do 'set seed = 0' before planning
a query.
heuristic determination of day vs month in date/time input. Add the
ability to specify that input is interpreted as yy-mm-dd order (which
formerly worked, but only for yy greater than 31). DateStyle's input
component now has the preferred spellings DMY, MDY, or YMD; the older
keywords European and US are now aliases for the first two of these.
Per recent discussions on pgsql-general.
only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON. Still TODO: provide some client-side autocommit
logic in libpq.
The first cleans up a couple of minor errors and ommissions
and adds tab completion support to more slash commands, e.g.
\dv.
The second is an attempt to add tab completion for schemas
and fully qualified relation names (e.g. public.mytable ).
I think this covers the TODO-item:
"Allow psql to do table completion for SELECT * FROM schema_part and table
completion for SELECT * FROM schema_name."
This happens via union selects querying:
- relation_name in current search path;
- schema_name;
- schema.relation_name
matching the current input string.
E.g:
SELECT p[TAB]
will produce a list of all appropriate relation names in the current search
path which begin with 'p', and also all schema names which begin with 'p';
\d pub[TAB]
will produce any relation names in the current search path and also
any schema names beginning with 'pub';
\d public.[TAB]
will produce a list of all relations in the schema 'public';
\d public.my[TAB]
produces all relation names beginning with 'my' in schema 'public'.
It seems to work for me; comments, suggestions, particularly regarding
the coding and queries, are very welcome.
Note that tables, indexes, views and sequences relations in the
'pg_catalog' namespace are excluded even though they are in
the current search path. I found not doing this produced annoying behaviour
when expanding names beginning with 'p'. People who work with system
tables a lot may not like this though; I can look for another solution
if necessary.

expression accepted by the regex operators, per discussion yesterday.
Along the way, reduce deadlock_timeout from PGC_POSTMASTER to PGC_SIGHUP
category. It is probably best to insist that all backends share the same
setting, but that doesn't mean it has to be frozen at startup.
necessarily following the JOIN syntax to develop the query plan. The old
behavior is still available by setting GUC variable JOIN_COLLAPSE_LIMIT
to 1. Also create a GUC variable FROM_COLLAPSE_LIMIT to control the
similar decision about when to collapse sub-SELECT lists into their parent
lists. (This behavior existed already, but the limit was always
GEQO_THRESHOLD/2; now it's separately adjustable.)
completion. Note that it's based on 7.3 tarball, not CVS HEAD, or 7.3rel
branch. Damn, looking at CVS, this will patch into 7.3rel (just tested,
it does) probably collide with Rod Taylor's patch adding ALTER TRIGGER
stuff. O.K, second patch attached against HEAD - not tested, hand
merged.
Ross Reedstrom
parameter to allow it to be forced off for comparison purposes.
Add ORDER BY clauses to a bunch of regression test queries that will
otherwise produce randomly-ordered output in the new regime.
Add simple ALTER DATABASE, ALTER TRIGGER, CHECK POINT, CREATE
CONVERSION, CREATE DOMAIN, CREATE LANGUAGE, DEALLOCATE, DROP CONVERSION,
DROP DOMAIN, DROP LANGUAGE, EXECUTE, PREPARE
Complete CAST in CREATE CAST and DROP CAST but doesn't suggest what
should follow.
Add many more SET / SHOW variables to the list. Taken from SHOW ALL

Complete a case sensitive search to allow \dD, \dd, \dS, \ds, \h, \H to
complete properly. But there are no matches, then try a case
insensitive search to allow case conversion. Add all missing help
options.
\Q<tab> -> \q
\dD<tab> -> \dD

precision for float4, float8, and geometric types. Set it in pg_dump
so that float data can be dumped/reloaded exactly (at least on platforms
where the float I/O support is properly implemented). Initial patch by
Pedro Ferreira, some additional work by Tom Lane.
to false provides more SQL-spec-compliant behavior than we had before.
I am not sure that setting it false is actually a good idea yet; there
is a lot of client-side code that will probably be broken by turning
autocommit off. But it's a start.
Loosely based on a patch by David Van Wie.
code review by Tom Lane. Remaining issues: functions that take or
return tuple types are likely to break if one drops (or adds!)
a column in the table defining the type. Need to think about what
to do here.
Along the way: some code review for recent COPY changes; mark system
columns attnotnull = true where appropriate, per discussion a month ago.
attstattarget to indicate 'use the default'. The default is now a GUC
variable default_statistics_target, and so may be changed on the fly. Along
the way we gain the ability to have pg_dump dump the per-column statistics
target when it's not the default. Patch by Neil Conway, with some kibitzing
from Tom Lane.
a few other things:
* Made all references to the pg_* tables absolute, by specifying
the pg_catalog schema.
* Added SCHEMA as a create/delete completion option.
* Added SCHEMA completion as: SELECT nspname FROM
pg_catalog.pg_namespace
WHERE substr(nspname,1,%d)='%s'
* Added completion of "INSERT INTO <table> (" with attribute names.
* Added completion of "INSERT INTO <table> (attribs)" with
VALUES or SELECT
* Added limited locking completion: only for one table:
"LOCK" and "LOCK TABLE" now both get a completion list of tables
Complete with "IN" for LOCK [TABLE] <table>
Complete LOCK [TABLE] <table> IN with a lock mode
* Added a very simple WHERE finisher that uses the previous word
as a table lookup for attributes.
* Added quote support when parsing "previous words". In other words,
hitting tab after INSERT INTO "foo bar baby"
now does the right thing and recognizes "foo bar baby" as one word.
Letting tab-complete quote things that should be quoted seems to be
temporarily ifdef'ed out due to readline compatibility problems.
Can anyone elaborate on this?

entries, per pghackers discussion. This fixes aggregates to live in
namespaces, and also simplifies/speeds up lookup in parse_func.c.
Also, add a 'proimplicit' flag to pg_proc that controls whether a type
coercion function may be invoked implicitly, or only explicitly. The
current settings of these flags are more permissive than I would like,
but we will need to debate and refine the behavior; for now, I avoided
breaking regression tests as much as I could.
path. The default behavior if no per-user schemas are created is that
all users share a 'public' namespace, thus providing behavior backwards
compatible with 7.2 and earlier releases. Probably the semantics and
default setting will need to be fine-tuned, but this is a start.
now just below FATAL in server_min_messages. Added more text to
highlight ordering difference between it and client_min_messages.
---------------------------------------------------------------------------
REALLYFATAL => PANIC
STOP => PANIC
New INFO level the prints to client by default
New LOG level the prints to server log by default
Cause VACUUM information to print only to the client
NOTICE => INFO where purely information messages are sent
DEBUG => LOG for purely server status messages
DEBUG removed, kept as backward compatible
DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1 added
DebugLvl removed in favor of new DEBUG[1-5] symbols
New server_min_messages GUC parameter with values:
DEBUG[5-1], INFO, NOTICE, ERROR, LOG, FATAL, PANIC
New client_min_messages GUC parameter with values:
DEBUG[5-1], LOG, INFO, NOTICE, ERROR, FATAL, PANIC
Server startup now logged with LOG instead of DEBUG
Remove debug_level GUC parameter
elog() numbers now start at 10
Add test to print error message if older elog() values are passed to elog()
Bootstrap mode now has a -d that requires an argument, like postmaster
when built against readline 4.2. Specifically, it handles the deprecation
of
filename_completion_function()
with preference for
rl_filename_completion_function()
Although, I was motivated by Cygwin support, IMO this patch is appropriate
for all platforms. To quote from the readline source:
#if 0
/* Backwards compatibility (compat.c). These will go away sometime. */
...
extern READLINE_EXPORT(char, *filename_completion_function) ...
#endif
Note that this patch is modeled after the one by Peter Eisentraut for
completion_matches():
http://www.ca.postgresql.org/~petere/readline42.html
I tested this patch under the following environments:
Cygwin with readline 4.1
Cygwin with readline 4.2
Linux with readline 2.2.1
Linux with readline 4.2
and it behaved as expected.

only if at least N other backends currently have open transactions. This
is not a great deal of intelligence about whether a delay might be
profitable ... but it beats no intelligence at all. Note that the default
COMMIT_DELAY is still zero --- this new code does nothing unless that
setting is changed.
Also, mark ENABLEFSYNC as a system-wide setting. It's no longer safe to
allow that to be set per-backend, since we may be relying on some other
backend's fsync to have synced the WAL log.
are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
accesses versus sequential accesses, a (very crude) estimate of the
effects of caching on random page accesses, and cost to evaluate WHERE-
clause expressions. Export critical parameters for this model as SET
variables. Also, create SET variables for the planner's enable flags
(enable_seqscan, enable_indexscan, etc) so that these can be controlled
more conveniently than via PGOPTIONS.
Planner now estimates both startup cost (cost before retrieving
first tuple) and total cost of each path, so it can optimize queries
with LIMIT on a reasonable basis by interpolating between these costs.
Same facility is a win for EXISTS(...) subqueries and some other cases.
Redesign pathkey representation to achieve a major speedup in planning
(I saw as much as 5X on a 10-way join); also minor changes in planner
to reduce memory consumption by recycling discarded Path nodes and
not constructing unnecessary lists.
Minor cleanups to display more-plausible costs in some cases in
EXPLAIN output.
Initdb forced by change in interface to index cost estimation
functions.
Initdb help correction
Changed end/abort to commit/rollback and changed related notices
Commented out way old printing functions in libpq
Fixed a typo in alter table / alter column
have the rl_completion_append_character variable. The tab completion
behavior doesn't seem to be quite perfect in that situation, but it's
better than failing to build at all...
rate
it's better than what used to be there.
* Does proper SQL "host variable" substitution as pointed out by Andreas
Zeugwetter (thanks): select * from :foo; Also some changes in how ':'
and ';' are treated (escape with \ to send to backend). This does
_not_
affect the '::' cast operator, but perhaps others that contain : or ;
(but there are none right now).
* To show description with a <something> listing, append '?' to command
name, e.g., \df?. This seemed to be the convenient and logical
solution.
Or append a '+' to see more useless information, e.g., \df+.
* Fixed fflush()'ing bug pointed out by Jan during the regression test
discussion.
* Added LastOid variable. This ought to take care of TODO item "Add a
function to return the last inserted oid, for use in psql scripts"
(under CLIENTS)
E.g.,
insert into foo values(...);
insert into bar values(..., :LastOid);
\echo $LastOid
* \d command shows constraints, rules, and triggers defined on the table
(in addition to indices)
* Various fixes, optimizations, corrections
* Documentation update as well
Note: This now requires snprintf(), which, if necessary, is taken from
src/backend/port. This is certainly a little weird, but it should
suffice
until a source tree cleanup is done.
Enjoy.
