Re: Limiting records in pg_dump

Thanks for that suggestion. Since I have a schema on the database, I could create the view on my schema or even a table with the same name with just the records that I want to copy to the other database. I had thought about the table but not necessary the view.

We are just in the process of looking at PostgreSQL as a solution to replace Oracle. Those high Maintenance and Support cost have made it necessary to find a replacement for Oracle.

you could create an alternate schema in your DB with VIEW's to your
database table(s) that filter it according to your requirements, then
pg_dump -n schemaname ....
