We have a cluster running 9.1.1 where pg_dump hangs when we try to dump
some a database inside of the cluster. The server is running AIX.
I can see this on clean cluster where we do an initdb, followed by a
createdb and try running pg_dump.
I've tracked the issue down to collectSecLabels in pg_dump.c
SELECT label, provider, classoid, objoid, objsbid FROM
pg_catalog.pg_seclabel;
returns 0 rows.
The code in collectSecLabels() is not prepared to deal with a zero row
result and tries to malloc 0 bytes.
I am not yet sure if the problem is that my pg_seclabel is empty or if
the issue is in collectSecLabels() or if collectSecLabels shouldn't even
be called.
Has anyone seen something similar?
