Not yet!

doing a pg_dump right now...

also, the OOM occurs in a copy event of a 2gb table.

droped work_mem to 2gb and trying again with psql  while doing a pg_dump

I just did "psql database < stuff.sql"

Hi,

Im trying to import a  9.4 database to a 9.5.1 system with psql but after few minutes I get OOM error...

Have 15gb ram.

Tried pgtune conf and still get error

shared_buffers = 3840MB 

effective_cache_size = 11520MB 

work_mem = 19660kB

maintenance_work_mem = 960MB 

min_wal_size = 1GB 

max_wal_size = 2GB 

checkpoint_completion_target = 0.7

wal_buffers = 16MB

Please, tell us how are you doing this exactly.

Did you try pg_dump, pg_restore?
