Обсуждение: 7.0.3 postmaster memory leak with aborted transactions

Test case:

create table test (data text unique);

Outside of psql, run this command (This is for bash):

while true ; do echo "begin work; insert into test (data) values ('This
is a test string.'); commit work;" ; done | psql

Watch the resident set size of the postmaster that the psql is connected
to as the while loop pumps data into psql.  As transactions are aborted,
the RSS of the postmaster continues to grow.  Looks like postmaster is
leaking memory somewhere.

Postgresql 7.0.3, compiled for Linux/glibc2 with gcc 2.95.2.

No is the answer.

Seems to be fixed in 7.1.
