[R] RdbiPgSQL and POSIXct

[Miha STAUT]

Hi,

Does the Bioconductor library RdbiPgSQL support the POSIXlt and POSIXct (R 
time format)?. I tried to import an R data frame which had also some columns 
of class POSIXct into PostgreSQL 7.2.1 with the command dbWriteTable without 
success.

>dbWriteTable(conn,jame,"j")

The same command produced a good result with the date columns transformed to 
factor.

THE ERROR MESSAGE
NOTICE:  current transaction is aborted, queries ignored until end of 
transaction block # the same error message repeated many times (I guess 
length(jame$x))

Thanks in advance, Miha Staut
