Here is an updated patch that uses different schema / role names for different tests (as per commitfest site feedback).
Short review about this version of the patch:
This patch work for me.
This test is a good thing and allows schema to be thoroughly tested, including corner cases which must fail because of errors or permissions.
Two remarks:
- test 2 bis: why name 'pg_asdf'? why not 'pg_schema_sch<some number>' to be homogeneous with other tests?
- test 3: why not WHERE schema_name='schema_sch3' instead of two negative comparisons? ISTM that if for some reason in the future a new schema name is added, the test will fail.
