Description: Out of memory when restore db
Details:

I made the backup of database named avtopzipbuh:
pg_dump -f%DRIVETO%\Backup\%DIRNAME%\%FILENAME% -Upostgres avtozipbuh
then, I tried to restore it:
psql -davtozipbuh -Upostgres -fF:\Backup\avtozipbuh
-oF:\Backup\logrestore.txt
but I had an error
"psql:F:/Backup/avtozipbuh:214116: ERROR: out of memory

===============

some parameters of my postgresql.conf
shared_buffers = 256MB
work_mem = 128MB
maintenance_work_mem = 16MB (tried change to 700Mb, no effect)

my system have 4Gb RAM, size of db approx 700mb. I have another db on this
system, its size 15Gb and I have no problem with it (dump\restore - ok)
