Re: Error while executing pg_dump "invalid memory alloc request size 4294967293"

Hi ,

Make sure no one is connected to the database while doing the back up.
Usually memory alloc error comes if its a bad RAM .
check the pg_dump version and your database version match (this could be a
guess)
try file level backup and restore into new database.
