[BioC] RDBIPgSQL: strange inheritance problems

[Dipl.-Ing. Johannes Rainer]

hi,

i just begun today in working with the RDBI packages and so i do not know if my
problem is trivial or not... anyway, i have my PgSQL running, and got my
connection to the database by the following command:

> Con <-
dbConnect(PgSQL(),user="postgres",host="localhost",dbname="TestDatabase")

when i try to list the tables from this database i get this strange error
message:

> dbListTables(Con)
Error in inherits(x, "factor") : Object "pattern" not found

are there any known problems with this packages i use (RDBI version 1.03 and
RDBIPgSQL version 1.06 freshly downloaded from the bioconductor home page).

i do not know from where i get this error and i suppose it is not a connection
or database problem, but some kind of different-version-conflict.

best regards,
jo
