Weird dbplyr error when the dev version of dplyr is installed

[krlmlr]

The symptoms are pretty weird. It seems that with the dev version of dbplyr the sql_escape_ident() generic isn't routed to the correct dbQuoteIdentifier() call. Haven't had time to investigate yet.

CRAN version

library(dbplyr)

my_db <- DBI::dbConnect(
  RMariaDB::MariaDB(),
  username = "guest",
  password = "relational",
  dbname = "Financial_ijs",
  host = "relational.fit.cvut.cz"
)

dplyr::tbl(my_db, "accounts")
