Re: Can a view use a schema search_path?

I have the feeling the answer is no, but I would like an
authoritative answer before I give up.

My plan was to have two schemas: one for the live data, and one for
staging, training, and testing.  Both schemas would have
identically-named tables.  I wanted to create a single view in the
public schema, and have that one view refer to the tables in one or
the other schema depending on my search_path setting at the time I
query the view.

But it seems that at the time the view is created it decides which
schema's table it's referring to, even if I don't explicitly qualify
the table names with the schema name.

Am I correct in concluding that there's no way to have a single view
in the public schema that selects data from tables in different other
schemas depending on my search_path at the time I execute a query
involving that view?


You could achieve this using a set returning function.
Inside the function you'd check the search_path and then dynamically build the approriate SELECT statement
