How to duplicate schemas in PostgreSQL

Question

I have a database with schema public and schema_A. I need to create a new schema schema_b with the same structure than schema_a

Answer 1

You can probably do it from the command line without using files:

pg_dump -U user --schema='fromschema' database | sed 's/fromschmea/toschema/g' | psql -U user -d database

Note that this searches and replaces all occurrences of the string that is your schema name, so it may affect your data.
