Hi all,

I did a database backup using the command:$ pg_dump -Ft -b mydb >
backupdb.tar

and now I'm tring to restore this backup using:$ pg_restore -d mydb
backupdb.tar
and I'm getting this error message: Segmentation fault (core dumped)

what is wrong? or what the best way to me backup my database and restore it
in other computer? which params should I use in pg_dump and pg_restore???

please help

What version(s) of PG are you using?  Have you tried using the
"custom" format (-Fc) rather than tar?  -Fc has worked pretty well for
me.

This is bad :-(.  Can you provide a stack backtrace from the core file?

I have seen this crash when the PostgreSQL shared libraries don't match
the pg_dump/pg_restore binary.
