pg_upgrade: out of memory

Hi,

I have attempted to upgrade my Postgres installation this morning from 9.0.1 to 9.2.0 and it failed with an out of memory problem using pg_dumpall to dump the first database.

So after backing out the change and restarting level 9.0.1, I've done some basic investigation into the failure of the 9.2.0 pg_upgrade by checking output in pg_upgrade_utility.log ...

command: "/opt/serviceMonitoring/postgres/bin/pg_dumpall" --port 50432 --username "postgres" --schema-only --binary-upgrade -f pg_upgrade_dump_all.sql >> "pg_upgrade_utility.log" 2>&1
pg_dump: out of memory
pg_dumpall: pg_dump failed on database "cahoot_monitoring", exiting

... rerunning pg_dump_all using existing version 9.0.1 ...

"/opt/serviceMonitoring/postgres/bin/pg_dumpall" --port 65432 --username "postgres" --schema-only --binary-upgrade -f pg_upgrade_dump_all.sql

... works fine.

Try with version 9.2.0 as per pg_upgrade ...

"/opt/serviceMonitoring/postgres_9.2/bin/pg_dumpall" --port 65432 --username "postgres" --schema-only --binary-upgrade -f pg_upgrade_dump_all.sql

pg_dump: out of memory
pg_dumpall: pg_dump failed on database "cahoot_monitoring", exiting

... tail -3 pg_upgrade_dump_all.sql ...

\connect cahoot_monitoring

... no help there.

Try with version 9.1.5 as per pg_upgrade ...

cd /tmp
"/opt/serviceMonitoring/postgres_9.1/bin/pg_dumpall" --port 65432 --username "postgres" --schema-only --binary-upgrade -f pg_upgrade_dump_all.sql

... works fine.

Has anyone else hit this problem ?
