The feature in itself is not extremely useful and instead PostgreSQL is
not always able to cast away from text[], which is a regression see
(ticket #42).
Dropped cyclic import from modules to tests: they were only working
because a second copy of the package was found in the project dir.
Use relative import so that 2to3 can do a good conversion.
Don't rely on Postgres casting the literal according to the context:
this doesn't work e.g. passing the object as function argument where a
function with the same name but taking a text exists. It doesn't work
either when the object is in an ARRAY construct.
Added test to check the type is respected in a complete Py -> PG -> Py
roundtrip without context.
Bug and solution reported by Peter Eisentraut.
* tests/*.py: use the DSN constructed in tests/__init__.py.
* tests/__init__.py: allow setting the host, port and user for the
DSN used by the tests through the environment.
patch from ticket #209 to check return value from
PyObject_AsCharBuffer(). This fixes the segfault.
(binary_quote): switch from PyObject_AsCharBuffer() to
PyObject_AsReadBuffer() to support buffer objects that don't
implement the bf_getcharbuf protocol.
* tests/types_basic.py (TypesBasicTests.testBinary): Test round
tripping of bytea buffers. Currently segfaults.
