Rjdbc consistently gives me an execution error with postgresql 9.0s JDBC4
driver. It's probably something trivial so am including my code below:

library("RJDBC")
param <- 249
param2 <- 188129
postgres <- JDBC("org.postgresql.Driver",
".m2/repository/postgresql/postgresql/9.0-801.jdbc4/postgresql-9.0-801.jdbc4.jar")
con <- dbConnect(postgres, "jdbc:postgresql://hq.d8u.us/erm", user =
"hdiwan")
sql <- "select id, startdate, value from dists where profileid = ?"
data1 <- dbGetQuery(conn, sql, param) # Dies here, no matter what the query,
tried with "select 1+1" as well as the one above
data2 <- dbGetQuery(conn, sql, param2)
cor(data1$V3, data2$V3)
