Things I'm impressed by pipe

When I dump DB data I usually do this way.

pg_dump -U postgres foo > dump.sql

Or

pg_dump -U postgres foo | gzip > dump.sql.gz

Then restore it from file. (Uncompress the file if you compressed the dump data)

psql -U postgres bar < dump.sql

But, if you use pipe, you don't need to dump it to a file.
Just send stream to a new DB!!

pg_dump -U postgres foo | psql -U postgres bar

It looks not so impressive. But, let's think two databases are located on each separated servers.
you can do this.

pg_dump -U postgres -h 192.168.0.1 foo | psql -U postgres -h 192.168.0.2 bar

Oh pipe! Thank god!! Thank person who made pipe!!! :-)
