Me and others are planning to move PG to ISO19100 compliance. ISO19100 is
the future standard that is describing GIS systems.
If you visit FMaps.sourceforge.net and go in the CVS you will see in the
directory /src/geoobj/ procedures to add geographic data types to PG. These
procedures need

MB == Memory Buffers?
If so then it shouldn't be the case for 7.0.X with Tom' work in bufmgr area.

No, it can't.
I have a patch which adds support for cursors in PL/pgSQL. If anybody
is interested, I can provide that pat
Hi,
today I did my first test with Oracle instead of PG (I had to really the boss
wanted it \:).
I have some perl-scripts using DBI, that insert a large amount of data, reduce
it and then create some report.
When I insert I do something like $dbh->{'AutoCommit'} = 0 and every 100,000

I wrote a plpgsql function/stored procedure to get around this problem.
I am not sure specifically what information you need about the row
after INSERT, but you could write a function that performs the INSERTs
and summing. After the initial INSERT you can use a SELECT INTO
statement to pass
We know we need to change INSERT rules to fire after the command.
Hopefully this will be done in 7.2.

records and growing.. and return 1k at time from the cursor. But, It I
also need to obtain the total number of records in the cursor without

Hello everybody,
We are trying to migrate an application from MySQL to PostgreSQL, and all
works fine except for a text based search we must do.
In MySQL we can run the next SQL sentence:
SELECT *, MATCH a,b AGAINST ('sample text') as x FROM t;
and it returns th

I have managed to change the length of a varchar field to 100 using:
update pg_attribute set atttypmod = 104 where attname = 'field_name' and
attrelid = (select oid from pg_class where relname = 'table_name');
I was wondering if I can do something similar to change the size of a
numeric fie

Hello,
I have just updated to 7.0 and have observed the following:
When the system boots, and Postgres is attempting to
start, I get the following error: 564, unary operator expected.
Yet after boot, I can see that postmaster is running and I
can connect to it with my application.
