Re: Search Path vs Synonyms

Ah, I am actually using EnterpriseDB (a commercial 'fork' of PSQL) which does have synonyms.

Is it possible set define the default search_path for a given user?

There are no synonyms in PostgreSQL: synonyms are Oracle's way
of search_path (though more selective).

You excluded the best solution, namely to qualify the objects.

If your user should be able to access *all* tables in both
schemas unqualified and there are no name collisions between
objects in the schemas, I would recommend search_path.

Otherwise, use views.
