I have worked on Federal, State and commercial projects and this is how any database object is referenced.
Not prefixing schema name along with the database object name will lead to several chaos situation in my opinion too.
Thanks,

Setting search_path to fix non schema qualified SQL, is not a Best Practice.
You CAN do this and it will work, but it CAN cause trouble if your database has things of the same name. (again a not Best Practice). My personal opinion on this, is to correct your SQL to include the schema qualified syntax (schema.whatever.) This way you are always 100% sure of what you are doing.

You don't. Instead, you set "search_path" to include both schemas. Yours, Laurenz Albe |
