Peter Harris (peter.harris@kyndal.co.uk) reports a bug with a severity of 2
The lower the number the more severe it is.
Short Description
python interface broken by removal of pg_type.typprtlen
Long Description
Version 7.3.1, pg_type seems to no longer have a column called typprtlen. This is OK by me, as that column is
considered'unused'.
However:
src/interfaces/python/pgdb.py expects it to be there, (line 150):
"SELECT typname, typprtlen, typlen "
"FROM pg_type WHERE oid = %s" % oid
ALL queries through pgdb.py fail with a traceback:
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/free/lib/python2.2/site-packages/pgdb.py", line 189, in execute
self.executemany(operation, (params,))
File "/free/lib/python2.2/site-packages/pgdb.py", line 221, in executemany
desc = typ[1:2]+self.__cache.getdescr(typ[2])
File "/free/lib/python2.2/site-packages/pgdb.py", line 149, in getdescr
self.__source.execute(
_pg.error: ERROR: Attribute "typprtlen" not found
The field is returned as part of the return value of the cursor.description() method for Python's DB API v2.0, but I
don't know of any requirement for what the value is.
Accordingly, I am working around this by replacing with:
"SELECT typname, typlen as typprtlen, typlen "
in pgdb.py
Sample Code
python
>>> import pgdb
>>> db=pgdb.connect(host=...,database=...,user=...,password=...)
>>> cur=db.cursor()
>>> cur.execute("select * from some_table")
... dies with traceback, as described.
