db_connection_describe() provides a short string describing the database connection, helping users tell which database a table comes from. It should be a single line, and ideally less than 60 characters wide.
dbplyr_edition() declares which version of the dbplyr API you want. See below for more details.
db_col_types() returns the column types of a table.
dbplyr 2.0.0
dbplyr 2.0.0 renamed a number of generics so that they could be cleanly moved from dplyr to dbplyr. If you have an existing backend, you'll need to rename the following methods.
dplyr::db_desc() -> dbplyr::db_connection_describe() (also note that the argument named changed from x to con).
