Since can generate a tbl() directly from a DBI connection we no longer
recommend using src_dbi().
src_dbi(con, auto_disconnect = FALSE)An S3 object with class src_dbi, src_sql, src.
An object that inherits from DBI::DBIConnection, typically generated by DBI::dbConnect
Should the connection be automatically closed when
the src is deleted? Set to TRUE if you initialize the connection
the call to src_dbi(). Pass NA to auto-disconnect but print a message
when this happens.
