I have Postgresql database that I would like to link to the geometry side of
Postgis. (This has little comparison to geography)
Does anyone know of a tool or documentation that could get me started??

Bob,
I don't quite understand your question. Are you not sure how to install
PostGIS, how

I have PostgreSQL, c/w the geometry attachment, installed on Win XP. I need to
get started using it. I am best able to do that by example, however
Does PostgreSQL use the COMMUTATOR property of an operator to determine
if flip-flopped arguments can be collapsed.
I used to think it did until someone pointed it doesn't - For example
in the below
SELECT b.*
FROM boszip b INNER JOIN landparcels l
ON (b.the_geom l.the_geom AND l.the_geom
I think I am missing something about how the new CREATE OR REPLACE
FUNCTION ...COST works or I am missing some setting in postgresql conf.
I was hoping I could use it to control the function that is used in
cases where only one needs to be evaluated. Regardless of what I do it
seems to always
--Test 2: This works as I would expect - shows that none of the
functions are run presumably its going straight for 5 2
--becuase it recognizes its the cheapest route
TRUNCATE TABLE log_call;
SELECT foo.value
FROM (SELECT (fn_pg_costlyfunction() 2 OR fn_pg_cheapfunction()
2 OR
5
Could still be a permission problem. Whatever NT account you are using
as the service account (usally called postgres) for the PostgreSQL
server is the one that needs to be able to create the postmaster.pid.
Make sure that account has full rights to the data folder.
Hope that helps,

Actually what you are doing below is trying to stuff '' in a timestamp
field.
Keep in mind '' and NULL are not the same. '' is invalid for timestamp
where as NULL is fine. Your example should be
insert into T_Admin(name,key,regDate,isLock,realName)
values('aaa','aaa',NULL,'1','aaa');

Well said Greg. I have the same problem too of having a crippled mail
reader :) Really I find mid posting hard to follow especially if I'm
the one that posted the question. I hope we aren't going to hit people
with hammers over this minor infraction. It really makes one feel
unwelcome.

I think PgAdmin ,in 1.8 at least, is by default set to hide system
objects like the template databases.
To enable this
go to File-Options-Display and make sure to check the Show system
objects in treeview. You may want to check some of the other options
as well.
Hope that helps,

Did you want to set to a specific known value or the min value of the
sequence. I think Pavel's sets to the min value of the sequence.
The below sets all the sequences to the same value
CREATE AGGREGATE sum ( BASETYPE = text,
SFUNC = textcat,
You could use a COALESCE instead of a case statement for simple case
like this. The below will treat a NULL as false and then when you do
not it becomes true. So NULLS will be set to true
UPDATE boolean_column SET boolean_column = NOT COALESCE(boolean_column,
false)
hope that helps,

As a side note, there is actually a book on design patterns in SQL,
although I personally haven't read it. From the reviews I recall reading
about it, I think its mostly based on Oracle Features. Still might be a
good read as far as PostgreSQL is concerned except for the sections on
Graphs and
I would do
select * into mynewtable
frommyoldtableORDER by random() LIMIT 15000
where 15000 in this case is your table row
count*.6
If you want to create another table with 40% of the
remaining data then something like
select * into mynewtable2 from myoldtable where
The short answer is that you leave out all the postgis function calls in
your dump, create a new database and load the postgis functions using the
new scripts. Then you just load the data.
I didn't find an easy way to selectively load tables and views using the
.sql format (and I actually
