Segmentation Fault during database restoration

Hi,

I am new to PostgreSQL. I have been trying to restore a compressed(.gz)
database using

gunzip -c *filename*.gz | psql *dbname*

After some 8 or 9 tables are restored the program exists giving error:
Segmentation Fault.

I have attached the crash report below.
