Hi All.
I've found a memory-leak bug in PostgreSQL 9.1.9's background
writer process.
When following parameter is set, it occurs every time CHECKPOINT runs.
wal_level = hot_standby
I've also confirmed REL9_1_STABLE and it is not fixed yet.
In additional, it also occurs in 9.3.beta1's checkpointer.
I created a patch (attached file) for 9.1.9,
so could anyone confirm?
Best regards.
