[R] crash on multiple queries to postgresql db

[Dylan Beaudette]

Hi,


Subsequent calls to:

conn <- dbConnect(PgSQL(), host="localhost", dbname="xxx", user="xxx")
query <- dbSendQuery(conn, query_text)
res <- dbGetResult(query) 

are resulting in this:

*** glibc detected *** /usr/local/lib/R/bin/exec/R: realloc(): invalid 
pointer: 0x0a605de4 ***
