Hello,

I have 2 RDS instances on AWS running PSQL 9.4.7.

I want to make a clone of database1 which belongs to user1, to database2 which belongs to user2. Database1 has 20+ tables. I want to avoid copying the DATA sitting on 5 tables on database1 (many Gigs).

I've read one too many posts about how to perform the actions with "pg_dump" and "pg_restore" but I'm trying to figure out the easiest way to do this. The process I have in mind is this:

1) pg_dump the schema from DB1 to DB2 using --no-owner and pg_restore with --role=user2
2) pg_dump -Fc --no-owner --data-only -t 'table1' from DB1 and then restore with pg_restore -t 'table' --role=user2 <table.sql> to DB2

This procedure though is very time consuming (although it could be scripted). Is there any better / faster / safer way to do this?

Thanks.
