Re: pg_dump fatal error

Hello,

What about trying to use a temporary file?

Something like:

ssh postgres(at)servidorslave01
/usr/pgsql-9.2/bin/pg_dump --exclude-table-data='junk.*' --format=custom
db_live > bigdump
/usr/pgsql-9.2/bin/pg_restore --dbname=uat_temp --exit-on-error bigdump

(no guarantee at all, I'm just blindly guessing!)

I usually do pg_dump's using plain SQL format: this allows to debug such
nasty surprises. It sometimes helps. In your case, I would do
something like:

ssh postgres(at)servidorslave01
/usr/pgsql-9.2/bin/pg_dump --exclude-table-data='junk.*' > bigdump.sql
# just to have a look at the dump:
less bigdump.sql
/usr/pgsql-9.2/bin/psql --dbname=uat_temp -f bigdump
