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. -- ... _._. ._ ._. . _._. ._. ___ .__ ._. . .__. ._ .. ._.

[GENERAL] 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 fails if 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 the 9.1 search_path. I suppose I shouldn't rely on undocumented features ... -- ... _._. ._ ._. . _._. ._. ___ .__ ._. . .__. ._ .. ._.
