02.11.2015 16:57, Barry Pederson:
The big issue with it is that it’s using version 2.0 of the pgsql
backend protocol. The current version is 3.0 introduced back in
PgSQL 7.4. (which is almost 12 years ago now). I’d imagine at some
point they’re going to want to drop support - although I haven’t seen
any actual announcements of that yet.
I'd say that we should contact PostgreSQL core devs and find out first.
Just saw your most recent commit.
Is this project now dead? Are there any working pure-Python PGSQL Django backends out there?
What version/revision of bpgsql are you using?
2.0alpha2
Which version of Python
2.5
Which version of PostgreSQL?
8.2.3
What steps will reproduce the problem?
1.Connect to DB
2.Execute Query
The query '''SELECT dt, nachricht, nachrichtlang FROM nachrichten ORDER BY
dt DESC %s''' %limit yields the following traceback:

return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 24-29:
unsupported Unicode code range
Am I using the it in a wrong way, or is this a bug?
Original issue reported on code.google.com by karl42 on 3 Nov 2009 at 5:12
I just fixed a bug I introduced when transitioning to Py3-compatible codebase that enabled Unicode strings to be passed with no SQL escaping. I am not the original author of this module and don't know the codebase yet - it should be checked for the possibility of an SQL injection.
