Dear List,
There are many opensource applications that support postgresql
(eg , gforge , bricolage , dspam ..) but does not use schemas(namespaces)
as a result of which you are forced to use/create a new database and loose
Hi ,
Is there any way to set a variable from a web application (using dbi/perl ,
libpq etc),
and access the same variable from a C trigger inside a transaction ?
the %_SHARED hash available in plperl provides only session level isolation
and
does not suit the requirement.

Hi ,
In certain C trigger function following code snippet causes ERROR:

data->time_stamp =
DirectFunctionCall1(timestamptz_in, CStringGetDatum("now"));

This code is incorrect, as timestamptz_in takes three arguments

Hi,
I am trying to interate over column names of a table on which a C trigger
function is called on UPDATE/DELETE and INSERT. SPI function
char * SPI_fname(TupleDesc rowdesc, int colnumber)
is being used. looks like the function is returning column names like
"pg.dropped.2" for d

You need to pay attention to the attisdropped field of the TupleDesc

Hi,
we know that rows in a table are not stored in any particular order
and explicit order by clause is required to get data in any particular
order.
but does it apply to select queries from ordered subselects also ?

if you have too many tables , generate the above commands
by using a query on tables information schema table.
hope it helps.

I think that's why pgAdmin does not work with plain backups on Restore.
What does occurs with the information schema when I restore from one database
with a name to other with another name ?

more methods:
1. select * from pg_stat_activity;
see what all running and pid of your current query also.
2. SELECT h.pid AS blocker, w.pid AS blockee
FROM ONLY pg_locks h, ONLY pg_locks w
WHERE h."granted" AND NOT w."granted" AND (h.relation = w.relation
AND h."database" = w."database" OR h.
Hi ,
looks like constraint exclusion is being too aggressive in excluding null values
although its well known that check constraints apply on not null values only.
Hope the minimal test session below explains the problem we facing.
BTW: we are very impressed with the performance gains we achieved
Update the phenomenon does not exists in 8.2.0 but exists in 8.2.5.

have you tried Join using , eg
SELECT e.eid, e.name
FROM entry e join access a ON( e.eid = 120
AND (e.ownid = 66 OR e.aid = a.aid) ) ;
some sample data might also help in understanding the prob
more clrearly.
