hi! i am experiencing the same behaviour explained here:
http://finzi.psych.upenn.edu/R/Rhelp02/archive/2482.html
(i copied the message below)
has anybody found a solution?
here is the code that gives me a segmentation fault
library(Rdbi)
library(Rdbi.PgSQL)
conn <- dbConnect(PgSQL(), dbname = "PGA")
tmp <- "create table test ( expid int, name varchar(128));"
result <- dbSendQuery(conn,tmp)
dbClearResult(result)
the last line can be substituted by
dbDisconnect(conn)
and you get a segmentation fault too.
The database PGA does exist and the dbSendQuery does create a table (i
checked via psql)
i followed the instructions given by tim (see url or msg below) and im
sending (what think is) the backtrace:
Program received signal SIGSEGV, Segmentation fault.

MESSGAGE from archive:
I've not seen this behavior. Try "R -d gdb" and then type
"run" at the
gdb prompt. Run your R session until the seg fault and send me the
backtrace. Thanks.
