I think only one schema other than TEMP or catalog is allowed in the search
path for the resolution of table name. I can call the schema the
CURRENT_SCHEMA.
If the restricted search path is inappropriate for the resolution of
function, type etc
name, you have to provide another path IMHO.
BTW every time I examined SQL99, I can find neither the description
CURRENT_SCHEMA == CURRENT_USER nor the one that the schema
name of an unqualified table name may vary according to the table name.
Probably it's because of my poor English. I'm happy if you could tell me
where to find it.
