In postgres search_path
variable set the priority for choosing the schema for the table:
search_path (string)
This variable specifies the order in which schemas are searched when an object (table, data type, function, etc.) is referenced by a simple name with no schema specified. When there are objects of identical names in different schemas, the one found first in the search path is used.
[...]
The current effective value of the search path can be examined via the SQL function current_schemas.
A quick way to do so:
SELECT current_schemas(True);
You can find details on how to manage search_path
in section 5.7.3. of this article: http://www.postgresql.org/docs/current/static/ddl-schemas.html
