Postgres 9.3 turns messages about implicit indexes and sequences from NOTICE
to DEBUG1 so the tests fail with a default 9.3 server configuration because
the client doesn't get any NOTICE. Fix it by also asking for DEBUG1 messages
from the server when testing against Postgres >= 9.3.
Unfortunately PQcancel blocks, so it's not better than PQgetResult.
It has been suggested to use PQreset in non-blocking way but this would give
the Python program the burden of handling a connection done but not configured
in an unexpected place.
TypeError is the standard Python error raised in this case:
$ python -c "(lambda a: None)(b=10)"
TypeError: <lambda>() got an unexpected keyword argument 'b'
We only used to raise InterfaceError when connect was used without
any parameter at all, so it's hard to think a program depending on
that design. Furthermore the function has always raised (and still
does) OperationalError too, if the bad argument is detected by the
libpq, and that cannot be changed because we can't tell the
difference from a normal connection error.
We don't need to look for stuff implicitly into pg_catalog as all
the builtin ranges are already registered. So just search into
'public' if the schema is not specified.
I was avoiding Numeric to avoid conflicting with the 'numeric'
Postgres type, which is an alias for 'decimal'. But now that there
is a single numeric range I can use the preferred name
In Python 3.3 items are returned as int instead of chars.
I'm not sure the way I did it is correct: worth asking some
hardcore Python dev.
Fixed tests after the stricter memview comparison rules in Py 3.3.
Pass a dumps function instead. Allow customizing by either arg passing or
subclassing.
The basic Json class now raises ImportError on getquoted() if json is not
available, thus allowing using a customized Json subclass even when the json
module is not available.
Makes invocation from subclasses and generic code easier.
Code simplified by using default values for keyword arguments
and avoiding needless conversions back and forth between Python and C
strings. Also added connection type check to cursor's init.
Failing to do so was causing the issue reported in ticket #103. The issue
as reported was fixed when SET ISOLATION LEVEL was dropped, but the real
problem wasn't fixed.
