Copies or tables in schema or copiyng of database - database versioning

[Łukasz Jarych <jaryszek@xxxxxxxxx>]

Hi Guys,

I want to create copies of tables in postgresql to use them by each user in coherent way, 

So version 1 will be schema1, version 2 will be schema2 (with copies of tables from version 1). 

How to perfom it ? 

Using pg dump and creating new schemas (or databases is a better idea)? 

Or it is a way to write sql to create new schema and copying the older one?

Best,

Jacek
