Hi.
I use libpq in my program. And I can retrieve int and symbolic fields
as simple as
int unameFN, moneyFN...
char *unamePTR, *moneyPTR...
unameFN = PQfnumber(res, uname);
moneyFN = PQfnumber(res, money);
unamePTR = PQgetvalue(res, 0, unameFN);
moneyPTR = PQgetvalue(res, 0, moneyFN);

IIRC, you need to keep calling PQgetResult until it returns NULL
before the connection is considered
I'm using libpq C Library. I prepared some query and trying to call it
many times.

Here is my testbed:

Can anybody briefly explain me how one postgres process allocate
memory for it needs?
There's no real maximum, as it depends on the exact usage. However, in
general postgres tries to keep below the values in work_mem and

related to maximum per-process data space. I don't know BSD very well
so I can't say if datasize is the only such value for BSD, but it'd be
worth checking. (Hmm, on OS X which is at least partly BSDish, I see

Hi.
Some hours ago there was a power failure with my test machine while
active inserting data. After power back the OS done some fsck, clean
some files (related to postgres working directory). Then I connect to
my DB and see this:
billing=# \d
ERROR: index pg_attribute_relid_attnum_index is
May I ask - how can I do it...? My ordinary startup command (from
rc.local) like this
# su -l _postgresql -c nohup /usr/local/bin/pg_ctl start -D
/var/postgresql/data -l /var/postgresql/logfile -o '-D
/var/postgresql/data'
But I tried
# su -l _postgresql
$ postgres -D /var/postgresql/data/ -P
10 matches
