Re: Backend memory leakage when inserting - Mailing list pgsql-general

Should have investigated this better before posting:

I have the following test case:
PostgreSQL 7.3.1 on i686-pc-linux-gnu, compiled by GCC 2.95.2 (running
a 2.2.23 kernel)
create an empty database
create table testdb(i integer,t timestamp);

edit a file fill.sql with 500 identical lines:
INSERT INTO testdb VALUES(1,'now()');

check memory of backend process (ps axuw): Column RSS 3224
\i fill.sql
backend RSS 3295 (ok, some sort of basic mem probably)
\i fill.sql ~ 10 times
backend RSS 3300
\i fill.sql ~ 25 times
backend RSS 3304
\i fill.sql ~ 70 times
backend RSS 3316

VSZ value is always the same (6248). So what's going on here ?


(now i have ~ 53500 tuples in my table)


I have no idea, what's going on here ? Any ideas ?
