This indicates that malloc() failed which means the system couldn't provide
any more memory. Either you have a very low memory ulimit (look at ulimit -a
in the same session as Postgres) or your machine is really low on memory.
Perhaps you have shared_buffers set very high or some other program is using
all your available memory (and swap)?

You're wrong. All the lines like:
> pg_attribute_relid_attnum_index: 1024 total in 1 blocks; 328 free (0
> chunks); 696 used
are a dump of Postgres's current memory allocations and could be useful in
showing if there's a memory leak causing this.
Also, what version of Postgres is this?
