Quickest command to dump and restore the database? : pg_dump and pg_restore? using PostgreSQL 8.3 running on RedHat 5.3
Hi all
I would like to know the quickest way of dumping and restoring the database in version 8.3 of PostgreSQL database running in RedHat 5.3.
We are currently using the command below, which seems to be very slow. We are moving from individual database to centralized database
pg_dump -U enterprisedb -Fc -t ${i} --data-only --ignore-version ${STORE_DB_HOST} -p ${DB_PORT} ${STORE_DB} | ${PG_BIN}/pg_restore -U enterprisedb -p ${DB_PORT} -t ${i} --data-only --dbname=${CDBS_DB}
Please assist…Thanks in advance
Thanks

Re: Quickest command to dump and restore the database? : pg_dump and pg_restore? using PostgreSQL 8.3 running on RedHat 5.3
pg_dump and restore are typically fast. Have you tried other -F
values? c does compression which, in your case, on your servers, might
be slow. You could also try running the dump on the server that is
hosting the source database, copying the file across and loading it on
the target server. Or some variation on that theme. Maybe that would
at least tell you which bit was slow.

Try this:
pg_dump –a source_db | psql target_db
