dbplyr 1.4.3

• dbplyr now uses RPostgres (instead of RPostgreSQL) and RMariaDB (instead of
  RMySQL) for its internal tests and data functions (#427).

• The Date and POSIXt methods for escape() now use exported
  sql_escape_date() and sql_escape_datetime() generics to allow backend
  specific formatting of date and datetime literals. These are used to
  provide methods for Athena and Presto backends (@OssiLehtinen, #384, #391).

• first(), last(), nth(), lead() and lag() now respect the
  window_frame() (@krlmlr, #366).

• SQL server: new translations for str_flatten() (@PauloJhonny, #405).

• SQL server: temporary datasets are now session-local, not global (#401).

• Postgres: correct str_detect(), str_replace() and str_replace_all()
  translation (@shosaco, #362).
