Postgre Server stopped during continuous run.

Hi,

I am new in PostgreSQL database.

I have a continuous running application that uses PostgreSQL as
database. This application inserts about 20 MB data into the database in
every second.I have disabled the WAL log , because all the data
inserting into the database is logged in the WAL files, that takes so
much space in the disc. My issue is that , after a two days continuous
run the Postgres server stopped unexpectedly . Can you explain what is
the reason behind this.? How can we recover from this. How can we use
Postgres database effectively in a continuous running application. Can
we specify the maximum size of WAL file that can be stored in the
database.On reaching the specified limit the older log files can be
deleted automatically.

Thanks & Regards,

Vishnu S
