per report from Olivier Prenant. Also fix off-by-one space calculation
in ReadToc; this woould not have hurt us until we had more than 100
dependencies for a single object, but wrong is wrong.
Example:
test=# \d test
Table "public.test"
Column | Type | Modifiers
--------+---------+-----------
a | integer | not null
Indexes:
"test_pkey" PRIMARY KEY btree (a)
Check Constraints:
"$2" CHECK (a > 1)
Foreign Key Constraints:
"$1" FOREIGN KEY (a) REFERENCES parent(b)
Rules:
myrule AS ON INSERT TO test DO INSTEAD NOTHING
Triggers:
"asdf asdf" AFTER INSERT OR DELETE ON test FOR EACH STATEMENT EXECUTE
PROCEDURE update_pg_pwd_and_pg_group(),
mytrigger AFTER INSERT OR DELETE ON test FOR EACH ROW EXECUTE PROCEDURE
update_pg_pwd_and_pg_group()
I have minimised the double quoting of identifiers as much as I could
easily, and I will submit another patch when I have time to work on it that
will use a 'fmtId' function to determine it exactly.
I think it's a significant improvement in legibility...
Obviously the table example above is slightly degenerate in that not many
tables in production have heaps of (non-constraint) triggers and rules.

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.

default datestyle. This is not portable between installations.
This patch sets DATESTYLE to ISO at the start of a pg_dump, so that the
dates written into the dump will be restorable onto any database,
regardless of how its default datestyle is set.
Oliver Elphick
now, my changes seem to work. Some possible minor bugs got squished
on the way but I can't be sure without more feedback from people who
really put the code to the test.
The new patch mostly simplifies variable handling and reduces code
duplication. Changes in the command parser eliminate some redundant
variables (boolean state + depth counter), replaces some
"else if" constructs with switches, and so on. It is meant to be
applied together with my previous patch, although I hope they don't
conflict; I went back to the CVS version for this one.
One more thing I thought should perhaps be changed: an IGNOREEOF
value of n will ignore only n-1 EOFs. I didn't want to touch this
for fear of breaking existing applications, but it does seem a tad
illogical.

changes to the SQL to retrieve attributes for older versions of Postgres is
probably wise. Also, please make sure that I have mapped the storage types
to the correct storage names, as this is relatively poorly documented.
I think that this patch might need to be considered for back-porting to
7.3.3 since at the moment, people will be losing valuable information after
upgrades.
Will dump:
CREATE TABLE test (
a text,
b text,
c text,
d text
);
ALTER TABLE ONLY test ALTER COLUMN a SET STATISTICS 55;
ALTER TABLE ONLY test ALTER COLUMN a SET STORAGE PLAIN;
ALTER TABLE ONLY test ALTER COLUMN b SET STATISTICS 1000;
ALTER TABLE ONLY test ALTER COLUMN c SET STORAGE EXTERNAL;
ALTER TABLE ONLY test ALTER COLUMN d SET STORAGE MAIN;

7.3.2). It removes some code duplication and #ifdeffing, and some
unstructured ugliness such as tacky breaks and an unneeded continue.
Breaks up a large function into smaller functions and reduces required
nesting levels, and kills a variable or two.

I changed the code to use sizeof - but will wait for a response from
Peter before changing the size. It's consistent throughout the sequence
code to be 100 for this purpose.

Envrironment and Files section, explained exactly what -w
does)
This is a patch which allows pg_ctl to make an intelligent
guess as to the proper port when running 'psql -l' to
determine if the database has started up (the -w flag).
The environment variable PGPORT is used. If that is not found,
it checks if a specific port has been set inside the postgresql.conf
file. If it is has not, it uses the port that Postgres was
compiled with.

> like that patch still needs some work...
Yeah. I'm really, really, *really* sorry for submitting it in the state
it was in. I shouldn't have done that just before moving to another
country. I found the problem last night, but couldn't get to a Net
connection until now.
The problem is in src/bin/psql/common.c, around line 250-335 somewhere
depending on the version. The 2nd and 3rd clauses of the "while" loop
condition:
(rstatus == PGRES_COPY_IN) &&
(rstatus == PGRES_COPY_OUT))
should of course be:
(rstatus != PGRES_COPY_IN) &&
(rstatus != PGRES_COPY_OUT))

implementation
of '\e' history tracking for systems that have a readline compatability
library without replace_history_entry. I fall back to pushing the query
onto the history stack after the \e, rather than replacing it.
The patch adds one more place to look for readline headers, and a test
for replace_history_entry. I've only included the patch for configure.in
Ross J. Reedstrom
RelOid_pg_class, and transaction locks XactLockTableId. RelId is renamed
to objId.
- LockObject() and UnlockObject() functions created, and their use
sprinkled throughout the code to do descent locking for domains and
types. They accept lock modes AccessShare and AccessExclusive, as we
only really need a 'read' and 'write' lock at the moment. Most locking
cases are held until the end of the transaction.
This fixes the cases Tom mentioned earlier in regards to locking with
Domains. If the patch is good, I'll work on cleaning up issues with
other database objects that have this problem (most of them).
