Hi!
Given this is an upgrade, though the specifics were omitted, is there some possibility of a pg_dump/server version mis-match being the cause. I could see where a 32-bit client connecting to a 64bit server could possible exhibit apparent memory-related issues.
pg_dump is 32-bit version. pg_dump -V returns pg_dump (PostgreSQL) 9.3.0 Server is x64 : PostgreSQL 9.3.3 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit Can this cause the issue ?Andrus.
