Hi,
I'm writing a server application in C that needs to interact with a postgre
database, but on my development server I'm getting tons of memory errors from
valgrind. There are enough of them that it's causing problems, like data
stored in a char* is magically changing after calling PQexec().
I'm
Woops, figured it out. Just needed to declare the num_var := '';

That answers a lot of my doubts with regard to search_path. Thanks!

hi, These codes are in the postgresql engine, just assume they are in
PortalRun() function:
//1.create table structure
char *relname = test;
...
relOid = heap_create_with_catalog(relname, );
CommandCounterIncrement();
...
//2.then i can use SPI_execute to create index on this created table
Hi,
Using the catalog tables, is there any way to correlate session id/user id
to which object (i.e. tables, indexes etc) it access and much how disk reads
or I/O wait has been done against the objects.
in general, I'd like to see which objects are being accessed by which user
and the time/amount

I have pgcrypto working fine with gpg keys that do *not* have a passphrase.

Hi all,
I'm seeing a funny behaviour in Postgresql 8.4.4. Namely, a query can
be executed using either of two different query plans, one taking a
few milliseconds and the other, tens of seconds. The work_mem setting
doesn't seem to affect it -- tried to increase or decrease it by 2 or
a cursory look of the plan details a FTS on dbmail_headername invoked by the
JOIN clause
JOIN dbmail_headername n ON v.headername_id=n.id
you would accelerate the seek appreciably by placing indexes on both
participating columns
v.headername_id
n.id
I also see a FTS on domain_headervalue

It seems that if the table in SELECT FROM has an explicit schema
specifier, further references to the same

Not out of the box.
The closest you'll get, AFAIK, is XML output from the SQLXML
