proposal for eventually deprecating OIDs on user tables that I posted
earlier to pgsql-hackers. pg_dump now always specifies WITH OIDS or
WITHOUT OIDS when dumping a table. The documentation has been updated.

offered for completion only when the input-so-far is at least 'pg_'.
This seems to be the best compromise behavior emerging from yesterday's
discussion. While at it, refactor code to eliminate repetitive use of
nearly identical queries, which was exceedingly tedious to maintain.
Also const-ify code more thoroughly in hopes of moving constant data into
text segment, and remove unnecessary length limit on queries.
"schema." has been typed. This allows readline to complete subsequent
characters immediately if all relations in the target schema start with
the same prefix. This actually worked before, but I unintentionally
broke it a few days ago.
Also, make completion schema-aware for GRANT, REVOKE, VACUUM.
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.
Ian Barwick
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
output.
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
\dd<tab> -> \dd
\D<tab><tab><tab> -> \d (with listing of \d? commands)
sel<tab> -> SELECT

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.
