Thread: faster inserting from dump?

hello.

how can i increase the speed of building a database from a dump?  there are
currently many tens-of-thousands of insert statements...i assume that a
commit is run after each statement?  i am guessing that it would be faster
if i commit after every hundred or thousand?  is there an easy way to tell
psql to do this?

please respond directly to me if it is not inconvenient.

thanks
chris

Correct... every statement is wrapped in an implicit transaction if an
explicit one is not provided.

Correct again.

Just use BEGIN; and COMMIT; to denote a transaction block. That's it!

You might also want to research the COPY command for doing bulks imports. I
personally use INSERTs because I need to have my importing error checked,
but if you can guarantee the integrity of the import, COPY is your best bet.
