Thread: How can I detect if a schema exists?

I was reviving an old test program which hasn't been used since 9.1 and found that "SET search_path = xyzzy" no longer
failsif the schema "xyzzy" doesn't exist. 

Is there an approved or recommended way to tell if a schema exists?  I can think of lots of ways, but none as easy as
the9.1 search_path.  I suppose I shouldn't rely on undocumented features ...

I'll have to play with the users and permissions, but that sounds like
it could be a feature; the code wants to know if the user can use the
schema.

I was wondering if there is a Postgres JDBC Type 4 wrapper for DB2 Federated
Server. The default wrapper from IBM has a number of issues with Postgres
which a better wrapper could solve. I will attempt to modify the IBM wrapper
if I can get my hands on the source code.
